Document Summary

Final exam: describe the purpose, structure, and organization of the circulatory system. Purposes: transport o2 and nutrients to tissues, remove co2 wastes from tissues, regulation of body temp. Closed loop circulates blood to all body tissues: describe the structure of the heart, flow of blood through the heart, and pulmonary versus systemic circuits. Inferior/superior vena cava, right atrium, right av (tricuspid) valve, right ventricle, pulmonary semilunar valve, pulmonary arteries, pulmonary circuit, pulmonary veins, left atria, left (bicuspid) av valve, left ventricle, aortic semilunar valve, aorta, systemic circuit, vena cava. Myocardium: middle layer, responsible for contracting and forcing blood supply via right/left coronary arteries, homogenous muscle containing primary fiber like type i. Cardiac muscle shorter fibers than skeletal, connected in tight series. Contraction (systole): ejects blood [atrial contraction occurs during ventricular diastole] At rest diastole longer than systole, during exercise systole and diastole shorter in duration (esp. diastole) As atria and ventricular chambers fill pressure rises.
