Closure of the atrioventricular valve occurs when the ventricles in the heart contract and blood is pumped to both lungs and body. The atrioventricular valve closes as a result of pressure generated by contraction of the ventricle muscles, which forces blood into the pulmonary artery and prevents backflow from entering into either chamber.

What Happens When the Atrioventricular Valve Closes?

Closure of the atrioventricular valve occurs when __. The atrioventricular valve closes as a result of pressure generated by contraction of the ventricle muscles, which forces blood into the pulmonary artery and prevents backflow from entering into either chamber.

With continued contractions of both ventricles, valves within these chambers close to prevent any more flow in one direction or another. The semilunar valves are located within each half-chamber (or hemisphere) and serve an important function during this process as well: They keep blood flowing through channels that lead only toward the lungs on top or body below for proper distribution to all parts
