ATI TEAS Secrets (TEAS 6) QUESTIONS AND ANSWERS ALL CORRECT Anatomy and Physiology Correct Answer: Flashcards Blood pressure Correct Answer: the force exerted on the vessels of the cardiovasucular system as blood is pumped through the body. Capillaries Correct Answer: the smallest blood vessels in the cardiovascular system. The thin network of vessels serves as the site of material exchange between arteries delivering blood and veins returning blood to the heart. Pulmonary ventilation Correct Answer: aka breathing. The process of air filling the lungs during inspiration (inhalation) and releasing air form the lungs to the atmosphere during expiration (exhalation) Bronchiole Correct Answer: are the small divisions of the bronchus, or air passage, found within the lungs. They connect to alveoli and transport gases in and out of the lungs during respiration. Larynx Correct Answer: hollow organ located in the neck on top of the trachea. In humans, the larynx contains vocal cords. As air passes. over the larynx during respiration, the cords vibrate and create sound that can be manipulated to make speech. Chyme Correct Answer: a mixture of partially digested food and digestive juices that forms in the. stomach and is passed through to the small intestine for further digestion. bile Correct Answer: an acidic fluid that is produced by the liver and stores in the gall bladder. Bile aids int he breakdown of fat macronutrients during digestion. Colon Correct Answer: a part of the large intestine that connects the cecum to the rectum. the largest part of the large intestine and is primarily responsible for water absorption and waste preparation. nephron Correct Answer: are small, fine tubes in the kidney that create urine and filter waste and other substances out of the blood. Spermatogenesis Correct Answer: the process fo sperms development in males. Spermatogonia which are sperm stem cells, give rise to spermatocytes in the seminiferous tubules within the testes. menstrual cycle Correct Answer: occurs in human females as well as other female primates. The process of ovulation (the release of the egg into the Fallopian tube) and menstruation, which is the shedding fo the egg and uterine lining in the event fertilization does not occur. somatic nervous system Correct Answer: a part of the peripheral nervous system and serves to control voluntary movement of the skeletal and muscle systems. Medulla oblongata Correct Answer: portion of the hindbrain that connects the brain to the spinal cord and is primarily responsible for regulation of autonomic bodily functions. visceral muscles Correct Answer: smooth muscle tissues found inside veins and arteries, the stomach, and other internal organs. These muscles involuntarily contract to move blood, food, or other substances from one place to another. They are so named because fo the lack of striations, or bands, found in other muscles. sarcomere Correct Answer: compromised of Bothe thick and thin filaments and is the basic unit found in myofibrils, which are the elongated organelles found within striated muscle tissue. As the muscles contract, the thick filaments slide by the thin filaments, thus shortening the myofibrils and causing muscle contraction. sesamoid bone. Correct Answer: small, rounded bone or nodule that is found within a tendon where the tendon passes over a joint. the patella is the largest example of a sesamoid bone. appendicular skeleton Correct Answer: the division fo the skeletal system that contains the bones of the appendages, or limbs, as well as the pectoral and pelvis girdles that attach to the axial skeleton. trophic hormones Correct Answer: are hormones that are produces in order to stimulate other glands to produce hormones. Most trophic hormones are produced by the anterior pituitary gland. melatonin Correct Answer: hormone produced by the spinal glands in order to control sleep and wake cycles. inflmmation Correct Answer: -itis nonspecific response to pathogens and injured cells. localized tissue releases histamines that raise the temperature and blood flow to the target area, which triggers more white blood cells to enter the area in order to repair it. antibodies Correct Answer: proteins produced by plasma that bind to the antigen protein found on the surface of pathogens. Once attached, the pathogen becomes neutralized and phagocytes are stimulated to ingest the target cell. hypodermis Correct Answer: Deep layer of skin that stores fat, which provides insulation and support for the body. melanocytes Correct Answer: skin cells that produce melanin in order to protect the skin from UV radiation through sun exposure. The melanin pigment also gives skin its color. thoracic duct Correct Answer: collects lymph from the majority of the human body, then drains lymph into the bloodstream tonsils Correct Answer: lymphatic nodules located in or near the pharynx. the human body has five tonsils which store t-cells and b-cells and aid the body in response to infection. atria Correct Answer: the chamber of the heart that receives blood from the lungs or other parts of the body. systole Correct Answer: contraction phase of the heartbeat, during which the heart ventricles force out blood into the lungs or to the body. external respiration Correct Answer: exchange of gases that occurs in the lungs at the alveoli pleura Correct Answer: the delicate membrane that covers and lines the human lungs peristalsis Correct Answer: muscular contractions that push food from one point to another within the digestive tract. absorption Correct Answer: the process of digested food moving into the bloodstream for cellular repsiration esophagus Correct Answer: the part of the digestive tract that transports food from the throat to the stomach by contracting its muscular walls. sphincter Correct Answer: a circular muscle that, when relaxed, allows materials to pass through for excretion.
