Drop of blood essay
venule, vein, superior vena cava, right atrium, tricuspid valve, right ventriclem chordae tendenae contract and valve closes, pressure pushes blood through pulm. semi lunar valve to pulm. artery, the valve closing causes the lub sound, pulm. system, to the pulm vein, left atrium, bicuspid/mytril valve, left ventrical, aortic semi lunar valve, aorta, coronary arteries feed the myocardium and dumps into coronary sinus and right atrium, ventricles relax or repolarize, the dup sound happens when the blood hits the semi lunar valves
