Today you will be learning about what the endocrine system is, and how hormones can interact within the endocrine system. Specifically, you will look at: 1. Endocrine System Overview 2. Opposing Hormone Interaction 3. Synergistic Hormone Interaction 4. Permissive Hormone Interaction 1. Endocrine System Overview The endocrine system is a body system that consists ofglands. Glands are clusters of cells that produce and secrete specific molecules such as hormones. Hormones are small signaling molecules (derived from either amino acids or lipids) that interact with target cells to change those cells' behavior in a way that promotes homeostasis. Many hormones play specific roles in specific parts of the body. Certain cells have a specific receptor for a particular type of hormone, ensuring that hormone can only affect those target cells. Because of this, not all cells are affected by all hormones.  TERMS TO KNOW Endocrine System A system of glands that produces and secretes hormones into the bloodstream; the endocrine system is used to communicate on a broad scale to the cells in the body Glands Glands are clusters of cells that produce and secrete specific molecules; endocrine glands secrete hormones directly into the bloodstream, where they can quickly reach their target cells anywhere in the body Hormones The major chemical messenger of the endocrine system, hormones, are produced, stored and secreted by glands; hormones either increase or decrease activity of the cells with which they interact Target Cell The cell or group of cells with which a hormone is designed to interact © 2019 SOPHIA Learning, LLC. SOPHIA is a registered trademark of SOPHIA Learning, LLC. Page 22. Opposing Hormone Interaction Hormones can actually interact with each other in order to produce different effects. One type of hormone interaction is an opposing interaction; where the effect of one hormone opposes the effect of another.  EXAMPLE Examples of opposing hormone interactions are insulin and glucagon. Insulin is a type of hormone that helps to lower sugar levels, while glucagon is a type of hormone that helps to increase blood sugar levels. There are certain situations when these hormones need to be released, such as after a meal (insulin) or when starved (glucagon), but not at the same time.  TERM TO KNOW Opposing Interaction A term used to describe hormones that create opposite effects of one another; an example would be that insulin lowers blood glucose while glucagon elevates blood glucose 3. Synergistic Hormone Interaction Sometimes hormones can create synergistic interactions, which means the two hormones cooperate with each other to affect a target cell.  TERM TO KNOW Synergistic Interaction A term used to describe hormones that create similar effects through slightly different mechanisms; an example would be that ADH stimulating kidneys retain water while aldosterone stimulates kidneys to retain sodium, which in turn retains water 4. Permissive Hormone Interaction A permissive interaction is when one hormone will prepare a cell for another hormone. For the second hormone to be able to affect the target cell, the target cell first has to be exposed to the first hormone. Think of it as one hormone will prep the cell for the other hormone to be able to take effect. The second hormone does not take effect until the cell has been exposed to the first hormone.  TERM TO KNOW Permissive Interaction When one hormone allows another hormone to have its full effect; an example would be thyroid hormones allowing growth hormone to have its full metabolic effects  SUMMARY This lesson has been a brief overview of the endocrine system and hormone interactions. Specifically, you looked at opposing, synergistic, and permissive hormone interactions. Keep up the learning and have a great day!

Page 3Endocrine System A system of glands that produces and secretes hormones into the bloodstream; the endocrine system is used to communicate on a broad scale to the cells in the body. Gland Glands are clusters of cells that produce and secrete specific molecules. Endocrine glands secrete hormones directly into the bloodstream, where they can quickly reach their target cells anywhere in the body. Hormones The major chemical messenger (derived from either amino acids or lipids) of the endocrine system. Hormones are produced, stored and secreted by glands; hormones either increase or decrease activity of the cells with which they interact. Opposing Interaction A term used to describe hormones that create opposite effects of one another. An example would be: insulin lowers blood glucose while glucagon elevates blood glucose. Permissive Interaction When one hormone allows another hormone to have its full effect. An example would be: thyroid hormones allowing growth hormone to have its full metabolic effects. Synergistic Interaction A term used to describe hormones that create similar effects through slightly different mechanisms.

Page 4Organs of the Endocrine System by Sophia Tutorial  WHAT'S COVERED Welcome to this lesson on organs of the endocrine system. Today you are going to be looking at a brief overview of the various organs and the hormones they secrete that are all associated with the endocrine system. Specifically, you will learn about: 1. Overview 2. Hypothalamus 3. Pituitary Gland 4. Pineal Gland 5. Thyroid & Parathyroid Glands 6. Thymus Gland 7. Pancreas 8. Adrenal Glands 9. Ovaries & Testes 1. Overview Below is a diagram of the various organs of the endocrine system and the hormones that they secrete. 2. Hypothalamus The hypothalamus produces hormones such as ADH and oxytocin. ADH is also known as the antidiuretic hormone and helps to regulate urination. Oxytocin is a hormone that plays a role in childbirth, among other things.  TERM TO KNOW Hypothalamus © 2019 SOPHIA Learning, LLC. SOPHIA is a registered trademark of SOPHIA Learning, LLC. Page 5The hypothalamus is at the "basement" of the forebrain, between the cerebrum and the midbrain/brainstem; the hypothalamus controls the activity of the pituitary gland. 3. Pituitary Gland The pituitary gland is a gland that works very closely with the hypothalamus. The pituitary gland stores and releases hormones that were produced in the hypothalamus. In addition, the pituitary gland also makes and secretes some of its own hormones, like growth hormone.  TERM TO KNOW Pituitary Gland Called the “master gland” because of its effects on other glands; the endocrine hormones increase activity/secretion of many major glands of the endocrine system. 4. Pineal Gland Another part of the endocrine system that we'll discuss is thepineal gland. The pineal gland is a gland that secretes melatonin, which is a hormone that plays a role in our sleep and wake cycles.  TERM TO KNOW Pineal Gland A gland located in the cerebrum that secretes melatonin, an important hormone for regulating sleep/wake cycles. 5. Thyroid & Parathyroid Glands The thyroid gland is located in front of the trachea (in men, it is just below the Adam's apple), and has a couple of different roles. The thyroid gland releases two main hormones: Thyroid hormone, abbreviated TH, which plays a role in metabolism and calcitonin, which is a hormone that plays a role in bone remodeling and blood calcium levels. Parathyroid glands are four tiny glands found on the thyroid gland and also play a role in bone remodeling.  TERMS TO KNOW Thyroid Gland The largest endocrine gland located on the anterior trachea, the thyroid gland secretes hormones that regulate metabolism; the thyroid gland also secretes a hormone called calcitonin that lowers blood calcium levels by increasing the kidneys' excretion of calcium and inhibiting osteoclasts. Parathyroid Glands A group of glands on the posterior thyroid that secrete parathyroid hormones to increase blood calcium levels by decreasing the kidneys' excretion of calcium and increasing osteoclast activity. 6. Thymus Gland The thymus gland releases thymosins; it is also where T cells mature, which are a part of our immune system.  TERM TO KNOW Thymus Gland A gland located above the heart; it secretes thymosins, which mature the immune system's T cells. © 2019 SOPHIA Learning, LLC. SOPHIA is a registered trademark of SOPHIA Learning, LLC. Page 67. Pancreas The role of the pancreas is to make and secrete insulin and glucagon. Insulin is a hormone that lowers blood sugar levels, and glucagon is a hormone that raises blood sugar levels. Somebody who has diabetes doesn't create or secrete the hormone insulin. Because of this, they have to take insulin injections to help lower blood sugar levels in their body.  TERM TO KNOW Pancreas The endocrine functions of the pancreas are to secrete insulin and glucagon to regulate blood glucose levels. 8. Adrenal Glands The two adrenal glands, found on top of the kidneys, are the next glands of the endocrine system we're going to talk about. Adrenal glands basically secrete the hormones epinephrine and norepinephrine, which create the fight or flight response that prepares the body for different types of stress. IN CONTEXT If you're in a dangerous situation, you get a rush of adrenaline. That feeling is coming from hormones the adrenal gland is releasing. It also sends out cortisol and aldosterone in response to stress.  TERM TO KNOW Adrenal Glands Located on top of the kidneys, the adrenal glands have two anatomic divisions: The adrenal cortex and the adrenal medulla. The adrenal cortex secretes hormones that regulate body mineral levels and metabolism and also aids in the production of sex hormones. The adrenal medulla releases hormones called catecholamines (adrenaline) that elevate our metabolism in response to stress. 9. Ovaries & Testes The female-specific organs of the endocrine system are theovaries. The ovaries release progesterone and estrogen, which are involved in the menstrual cycle and pregnancy, among other things. The male-specific organs of the endocrine system are the testes. The testes make and secrete testosterone, which is involved in the production of sperm, among other things.  TERMS TO KNOW Ovaries The primary sex organs of females and the primary source of estrogen and progesterone; the ovaries are also where the eggs are matured and released. Testes The primary sex organs of males and are the primary source of testosterone; the testes are also where sperm is produced and matured.  SUMMARY This lesson has been an overview of the various glands of the endocrine system, as well as the different hormones that those organs create and secrete.

In this lesson you will look at: 1. Hormone Overview 2. Steroid Hormones 3. Non-Steroid Hormones 4. Secondary Messenger 1. Hormone Overview Hormones are chemical messengers (derived from either amino acids or lipids) of the endocrine system. They are made and secreted by glands. Once secreted, hormones interact with specific types of cells, signaling the cell's activity to change in some way. Cell receptors are specific to the hormones they interact with, and certain types of hormones can only affect certain types of cells. This means that not every hormone affects every type of cell because not all cells will possess their receptors. 2. Steroid Hormones Steroid hormones are lipids that are made from cholesterol. They're produced in the adrenal glands and reproductive glands. Because steroid hormones are lipids made from cholesterol, they are non-polar, hydrophobic (water-repelling) molecules. This means they can't move through blood (which is very watery) without help, but they can move through the plasma membrane easily. They get to make a direct path through the cell to receptors on the nucleus. Steroid hormones will bind to receptors on the nucleus, and this will allow them to affect the behavior of the DNA. They can turn genes and DNA on or off; this controls protein-making mechanisms and can directly affect the target cell's function.  EXAMPLE Examples of steroid hormones are estrogen (which is involved in female reproduction) and testosterone (which is involved in male reproduction).  TERM TO KNOW Steroid Hormones Hormones that have a cholesterol backbone and are not soluble in water due to their lipid structure; steroid hormones are transported through the blood attached to carrier proteins; steroid hormones penetrate the cell membrane and interact with nuclear receptors that affect DNA transcription. 3. Non-Steroid Hormones Non-steroid hormones are derived from amino acids; as a result, they tend to be more polar/hydrophilic (water-attracting). This means that they can pass easily through the blood (which is very watery), but cannot pass through the target cells' plasma membranes. Instead, non-steroid hormones bind to receptors on the target cell's plasma membrane.  TERM TO KNOW © 2019 SOPHIA Learning, LLC. SOPHIA is a registered trademark of SOPHIA Learning, LLC. Page 10Non-steroid Hormones A class of hormones that are primarily derived from amino acids and are water soluble due to their polar nature; non-steroid hormones are transported freely through the blood; non-steroid hormones interact with receptors on the cell membrane and activate secondary messenger systems that carry out their effects within the cell. 4. Secondary Messenger Remember, steroid hormones bind to receptors on the nucleus, and non-steroid hormones are going to bind to receptors on the target cell's plasma membrane. Because non-steroid hormones aren't able to pass through the plasma membrane, they will activate what are called secondary messengers. Secondary messengers relay information to the interior of the cell. When non-steroid hormones bind with their receptors on the plasma membrane, the secondary messenger will be activated. The secondary messenger will then relay the signal ultimately to the DNA, where changes in the target cell's behavior are controlled.  TERM TO KNOW Secondary Messenger A group of signaling molecules located near a hormone receptor on the inside of the cell; when a non-steroid hormone binds to its receptor, it activates secondary messenger systems that carry out specific effects inside of the cell. Non-steroid hormones rely on secondary messenger signaling molecules because they are unable to penetrate the cell membrane and get into the cell.  SUMMARY This lesson has been an overview of hormones, including steroid and non-steroid hormones and secondary messengers.

Today you will be discussing the kidney's role in maintaining the blood pH. Specifically, you will be learning about: 1. pH Balance Overview 2. pH Management 1. pH Balance Overview Kidneys are organs of the body that help maintain the body'sacid-base balance. Acid-base balance is the amount of acids and bases found in extracellular fluids of the body. Acids are substances that increase the amount of hydrogen ions (H+) in a liquid and lower thepH. For example, distilled vinegar is an acid of around pH 2 or 3. That means it's at least 10,000 times more acidic than water, which has a neutral (neither acidic nor basic) pH of 7. When added to warm milk, it changes the shape of milk proteins into curds that can be made into cheese. Stomach acid also has a pH of about 2 or 3; you can imagine how effective stomach acid is at curdling the proteins in potentially infectious bacteria! Bases are substances that decrease the amount of hydrogen ions (H+) in a liquid and raise the pH. Baking soda is a mild base (pH 9); it's about 100 times less acidic than water. This can be a problem for the Electron Transport Chain. Remember, you need to have a certain amount of hydrogen ions in the intermembrane space of your mitochondria to create an electrical chemical gradient needed to make ATP. If your blood is too basic, it means hydrogen ions are in short supply, and making enough ATP to function well will be more difficult. Normal body pH is between 7.37 to 7.43. If you're familiar with the pH scale, you know that a pH of seven is neutral, a pH of less than seven is acidic, and a pH of more than seven is basic. If our pH is 7.37 to 7.43, that's slightly more than seven, which means the normal pH of the body is slightly basic. For our body to function properly, for our cells and enzymes to function optimally, pH needs to stay within this range. If blood pH drops to 7.36, for example, it is still technically more basic than water, but it is too acidic for our proteins to function well (think of milk proteins curdling in vinegar). Likewise, if blood pH rises to 7.44, it's too basic for proteins to function properly.  TERMS TO KNOW Acid-Base Balance The amount of acids and bases in the extracellular fluids of the body; amounts of acids vs. bases affects the overall pH of extracellular fluids. Acids Substances that increase the amount of hydrogen ions (H+) in a liquid and lower the pH. Bases Substances that decrease the amount of hydrogen ions (H+) in a liquid and raise the pH. pH A measure of whether a liquid has a lot of hydrogen ions (H+) or relatively few hydrogen ions; the lower the pH, the more hydrogen ions it has, and the more acidic it is, the higher the pH, the fewer hydrogen ions it has, the more basic it is © 2019 SOPHIA Learning, LLC. SOPHIA is a registered trademark of SOPHIA Learning, LLC. Page 1212. pH Management pH is largely managed by the amount of carbon dioxide dissolved in your blood. When carbon dioxide (CO ) dissolves in your blood plasma, it interacts with a water molecule (H O) to become carbonic acid (HOCOOH or H CO ). However, above a pH of ~6, carbonic acid would rather split into bicarbonate and a hydrogen ion (HOCOO- and H+). This means that in your blood (pH ~7.4, well above pH 6), dissolved carbon dioxide will generate hydrogen ions, making your blood more acidic and lowering the pH. What happens when there's not enough carbon dioxide dissolved in your blood? It means that there are not enough hydrogen ions being generated, so your blood becomes more basic, and your blood pH rises. This is what happens if you hyperventilate: You're breathing so hard that more carbon dioxide is leaving your blood through your lungs than your metabolism (converting acetyl-CoA into carbon dioxide through the Krebs Cycle, for example) can quickly replace. Your blood pH rises, and you may even faint.  SUMMARY This lesson has been an overview of how the kidneys help to maintain the body's acid-base balance.

Today, you’re going to be learning about various disorders that can affect kidneys. Specifically, you will learn about: 1. Kidney Stones 2. Urinary Tract Infections 3. Nephritis 4. Kidney Cancer 5. Dialysis 6. Alcohol Consumption 1. Kidney Stones Kidney stones can develop from minerals or other substances that are found in urine. These can be things like uric acid or calcium salts that settle out of urine to form these kidney stones. Kidney stones can range in size from being pretty small to fairly large. If a kidney stone is small enough, it'll end up just passing out of the body with the urine. If they're large enough, they can become very painful as they move through the urinary system and can clog up different parts of the urinary system. They may get clogged in a ureter, which connects a kidney to the urinary bladder. At that point, the person would have to go to the doctor and get some sort of treatment to break this kidney stone down into a size small enough to pass. This can be a very painful process and may also cause damage to the lining of ureters.  TERM TO KNOW Kidney Stones Deposits of acids and salts that accumulate in the kidneys and can obstruct the flow of urine; kidney stones are very painful to void. 2. Urinary Tract Infections Urinary tract infections are caused when bacteria from outside the body make their way into the bladder and cause inflammation. They are actually more common in women because they have a much shorter urethra than men, so it's much easier for bacteria to travel up a short urethra and into the bladder than up a very long urethra and into the bladder.  TERM TO KNOW Urinary Tract Infection (UTI) Infections that enter the urethra and can climb as high as the kidneys, UTIs cause inflammation of the urinary bladder or kidneys. 3. Nephritis Nephritis is the inflammation of the kidneys, which can be caused by bacterial infections, among other factors, © 2019 SOPHIA Learning, LLC. SOPHIA is a registered trademark of SOPHIA Learning, LLC. Page 123and result in pressure build up around capillaries. Filtration of blood then becomes ineffective. Because of its hard outer covering, the kidney has a hard time swelling if fluid accumulates within it. Remember that the renal arterioles are very narrow, so blood pressure is relatively high when it enters the glomerulus (just like when you put your thumb over the water stream of a hose, making the spray shoot harder and further). It's this pressure that forces the water and solutes of the blood plasma into the Bowman's capsule for filtration. If there's back-pressure (if there's inflammation of the kidneys pushing back on the pressure from the renal arterioles), the total pressure of the blood plasma on the capillaries of the glomerulus is less. The result is less fluid being forced from the blood into the Bowman's capsule, so filtration is far less effective.  TERM TO KNOW Nephritis Inflammation of the kidneys caused by infections or autoimmune disorders. 4. Kidney Cancer Kidney cancer is a cancer of the kidney, as the name implies. This type of cancer can actually spread very easily through the bloodstream because kidneys filter the blood. If the kidneys have cancer, it can be fairly easy for some of those cancerous cells to basically flow with the blood and implant themselves in another part of the body. Kidney cancer can spread easily throughout the body due to its access to the bloodstream. Bladder cancer is another cancer that is closely related to the kidneys. Both bladder cancer and kidney cancer are more common in men than they are in women.  TERM TO KNOW Kidney Cancer Cancer that occurs in the kidneys; it is more prevalent in males than in females. 5. Dialysis Dialysis is a process in which a machine will clean the blood if the kidneys are unable to. If a person has some sort of kidney disorder, where kidneys are not properly functioning, they can't properly filter the blood. Dialysis is the process in which a machine will filter blood for them. A dialysis machine cleans the blood and helps maintain the volume and composition of extracellular fluids.  TERM TO KNOW Dialysis The process of artificially filtering a person’s blood by pumping it out of their body and into a machine; dialysis is a necessary procedure for a person whose kidneys are failing or completely gone (failed). 6. Alcohol Consumption Consumption of alcohol is another factor that can have an effect on kidney health. Consumption of alcohol will inhibit ADH, which stands for anti-diuretic hormone. This causes the body to lose more water, and as the body loses more water, the concentration of ions will be upset, and balance will be altered. Alcohol causes the kidneys to increase urinary output, which will then lead to dehydration. If a person heavily drinks over a long period of time throughout their life, it can actually lead to much more serious kidney disorders in the future.  SUMMARY This lesson has been an overview on kidney disorders and health.
