Endocrine System
Gland/Organ Hormone Secreted Function
Hypothalamus Releasing/Inhibiting hormones Stimulate Pituitary
Anterior Pituitary (base of brain; controls growth and development Adrenocorticotropic Hormone (ACTH) Stimulate adrenal cortex to secrete glucocorticoids
Thyroid Stimulating Hormone (TSH) Stimulate the Thyroid gland
Follicle Stimulating Hormone (FSH) Stimulates production of ova (females) and sperm (males)
Luteinizing Hormone (LH) Stimulates Ovaries (females) and Testes (males)
Prolactin Stimulates milk production
Growth Hormone (GH) Stimulates growth (bones) and metabolic functions
Posterior Pituitary (back of anterior pituitary) Antidiuretic Hormone (ADH) Promotes retention of water by the kidneys
Oxytocin Stimulates contraction of uterus and mammary gland cells
Pineal Gland (center of brain) Melatonin Sleep cycles; biorhythms
Thyroid (neck; hormones regulate growth, development, and metabolism) Triiodothyronine (T3) Metabolism
Thyroxine (T4) Metabolism and temperature
Calcitonin Inhibits release of Calcium from bones
Parathyroid (4 glands on Thyroid) Parathyroid Hormone (PTH) Stimulates release of calcium from bones, back into blood.
Thymus (lymphoid organ that produces T-Cells) Thymosin Stimulates T-Cell Development
Adrenal Glands (Above Kidneys; regulate HR, BP, and other functions) See below See below
Adrenal Cortex (stimulates fight or flight response) Cortisol/Glucocorticoids Stress response; Increase blood glucose, Decrease immune response; metabolism
Aldosterone Regulates Na content in blood
Adrenal Medulla (stimulates Epinephrine Fight

fight or flight response) Norepinephrine Flight
Ovaries (female gonads) Estrogen Stimulates egg maturation, controls 2ndary sex
TEAS 6 Science
characteristics
Progesterone Prepares uterus to receive fertilized egg
Testes (male gonads) Testosterone Regulates sperm production and 2ndary sex characteristics
Kidneys Erythropoietin Response to cellular hypoxia
Renin Promotes production of Angiotensin
Liver Angiotensin II Vasoconstriction, Increase BP
Pancreas Glucagon (Alpha Cells) Increase blood glucose
Insulin (Beta Cells) Decrease blood glucose
Stomach Gastrin Response to food; stimulates production of gastric juices
Intestine Secretin Response to acidity in small intestine; stimulates secretion by liver and pancreas
Cholecystokinin Production of Bile Salts
Heart Atrial Natriuretic Peptide (ANP) Increase renal Na excretion, decrease ECF
