Atrial natriuretic peptide (ANP) - CORRECT ANSWER made in the heart - puts Na in urine, decreasing blood volume renin - CORRECT ANSWER An enzyme secreted by the juxtaglomerular cells in kidney when blood pressure decreases - converts angiotensinogen to angiotensin I - indirectly secrets aldosterone Erythropoietin (EPO) - CORRECT ANSWER hormone secreted by the kidneys; targets bones, (red bone marrow) which stimulates red blood cell formation (tells stem cells to become RBC) - which increases oxygen carrying capacity epinephrine and norepinephrine - CORRECT ANSWER aid body during stress by raising heart rate, blood pressure, and respiration - made in adrenal medulla Acetocholine (Ach) - CORRECT ANSWER first neurotransmitter to be identified; released at neuromuscular junctions; enables muscle action, learning and memory 4 layers of alimentary canal - CORRECT ANSWER mucosa (mucus membrane), submucosa (supports passage of blood vessels and nerves), muscularis (2 layers, circular and longitudinal), serosa (simple squamous and loose connective) alimentary canal - CORRECT ANSWER the whole passage along which food passes through the body from mouth to anus. It includes the esophagus, stomach, and intestines. circular and longitudinal muscles - CORRECT ANSWER cause peristalsis circular: squishes down longitudinal: shortens
