Document Summary

Provide addiional support for great vessels & valves. Direct spread of acion potenials across heart to speciic pathways: endocardium. Layer of endothelium + ct layer on inner myocardial surface. Coninuous with endothelium of vessels leaving & entering heart. 4. 2. 1. 3 locate the following on diagrams of the heart: chambers, great vessels, coronary circulaion, internal muscles, etc: 2 atria & 2 ventricles; what are the interatrial. 2 side-by-side pumps: pulmonary circuit (lungs, systemic circuit (let heart) Oxygen poor blood on the right side, oxygenated blood is on the let side. Let ventricle pumps blood to aorta: internal walls have muscle bundles: trabeculae carneae (control bowel funcion), papillary muscles (controls valve funcion, heart valves. Blood low is unidirecional; enforced by 4 heart valves. Blood remains in ventricles, pressure cannot be generated) vs stenosis (valves openings become ight harder to pump blood) 4. 2. 2. 2 difereniate between the pathways of the pulmonary and systemic circuits: oxygenaion of the blood, workload, structure of ventricular wall.
