Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
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: -When the left ventricle contracts, the mitral valve closes and the aortic valve opens. This is so blood flows into the aorta and out to the rest of the body. While the left ventricle is relaxing, the right ventricle also relaxes. This causes the pulmonary valve to close and the tricuspid valve to open.
Detailed explanation-2: -Mitral Valve Separates the top left chamber (left atrium) from the bottom left chamber (left ventricle). 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: -The mitral valve regulates the blood flow between the left atrium and the left ventricle. It prevents the backflow of blood to the left atrium when the left ventricle pumps blood through the aorta to the rest of the body.
Detailed explanation-4: -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.
