|
opens to allow blood to the left ventricle, then closes to prevent blood from flowing back into left atrium
|
|
|
closes to prevent regurgitation of blood from the right ventricle back into right atrium
|
|
|
closes off the lower left chamber that holds the oxygen-rich blood before it is pumped out to the body.
|
|
|
blood flows from right ventricle through pulmonary valve to pulmonary artery and then into the lungs, where it picks up oxygen to deliver to your body
|
Detailed explanation-1: -The pulmonary valve prevents blood from going backward from the pulmonary artery to the right ventricle. Mitral valve: This valve has two leaflets. They allow blood to flow from the lungs into the left atrium. And they prevent backward flow from the left ventricle to the left atrium.
Detailed explanation-2: -Mitral Valve Opens to allow blood to flow from the left atrium to the left ventricle. Prevents the back flow of blood from the left ventricle to the left atrium.
Detailed explanation-3: -When the two atrium chambers contract, the tricuspid and mitral valves open, which both allow blood to move to the ventricles. When the two ventricle chambers contract, they force the tricuspid and mitral valves to close as the pulmonary and aortic valves open.
Detailed explanation-4: -As the left atrium contracts, more blood flows into the left ventricle. When the left ventricle contracts, the mitral valve closes and the aortic valve opens, so blood flows into the aorta.
