Pump blood away from the heart: valves, open and close to control blood low through the heart, atrioventricular valves, tricuspid valve b/w right atrium and ventricle. 3 laps or cusps: bicuspid valve b/w let atrium and ventricle. Let atrium pumps blood through bicuspid valve to the let ventricle. Let ventricle pumps blood through the aoric semilunar valve to the systemic circuit v. vi: oxygen-poor blood never mixes with oxygen rich blood (in humans) c.
