When the ventricles contract, the bicuspid valve prevents blood from flowing from the ____
|
|
right ventricle to right atrium
|
|
|
left ventricle to left atrium
|
|
|
left atrium to the right atrium
|
|
|
right atrium to the left atrium
|
Explanation:
Detailed explanation-1: -The bicuspid valve prevents backflow from the left ventricle into the left atrium. The semilunar valves prevent backflow into the ventricles from the aorta and pulmonary arteries.
Detailed explanation-2: -When the ventricular walls contract (specifically, the walls of the left ventricle), the bicuspid/mitral valve closes to prevent blood from flowing into the left ventricle from the left atrium, when the left ventricle relaxes, the bicuspid valve opens to allow blood to flow from the left atrium into the left ventricle.
Detailed explanation-3: -The valve allows blood to flow from the left ventricle (pumping chamber) to the aorta and prevents blood from flowing backward.
