Atria Minimal role in pumping blood 11/16/2018 Atria Minimal role in pumping blood auricles - earlike hollow appendages used as an overflow move the blood to the ventricles

Ventricles Muscular chambers thick layer of myocardium 11/16/2018 Ventricles Muscular chambers thick layer of myocardium left wall is thickest trabeculae carnea connect to papillary muscles attach to valves

Valves Tricuspid valve Pulmonary semilunar valve 11/16/2018 Valves Tricuspid valve between rt. atrium & ventricle Pulmonary semilunar valve between rt. ventricle & pulmonary trunk Mitral valve (bicuspid) between left atrium & ventricle Aortic semilunar valve between left ventricle & aorta

11/16/2018 Blood flow Deoxygenated blood enters the heart from the inferior vena cava, superior vena cava, and the coronary sinus From rt atrium to rt ventricle through the tricuspid valve From rt ventricle to pulmonary trunk through the pulmonary semilunar valve

11/16/2018 Blood flow From the pulmonary trunk to the rt and left pulmonary arteries to the lungs Oxygenated blood returns from the lungs in the pulmonary veins to the left atrium From the left atrium to the left ventricle through the bicuspid valve

11/16/2018 Blood flow From the left ventricle to the aorta through the aortic semilunar valve From the aorta to the rest of the body Back to the right atrium through the inferior vena cava, superior vena cava, and coronary sinus
