|
|
|
closes off the lower left chamber that holds the oxygen-rich blood before it is pumped out to the body
|
|
|
opens to allow blood to the left ventricle, then closes to prevent blood from flowing back into left atrium
|
|
|
closes when the ventricle squeezes blood out to the lungs and then opens to let more blood into the ventricle.
|
|
|
valve acts as a doorway that lets blood into and out of the heart
|
Detailed explanation-1: -Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle. When your right ventricle is full it squeezes, which closes your tricuspid valve and opens your pulmonary valve. Blood flows through your pulmonary artery to your lungs, where it gets oxygen.
Detailed explanation-2: -After the atria fill with blood, the mitral and tricuspid valves open to allow the blood to flow from the atria into the ventricles. When the ventricles contract, the mitral and tricuspid valves close while the blood is pumped outward through the pulmonary and aortic valves to the lungs and body.
Detailed explanation-3: -When the right atrium fills, the tricuspid valve opens, letting blood into the right ventricle. Then the right ventricle contracts to send blood to the lungs. The tricuspid valve closes tightly so that blood does not go backward into the right atrium.
Detailed explanation-4: -Tricuspid valve: Allows blood to pass from the right atrium to the right ventricle; prevents blood from flowing back into the right atrium as the heart pumps (systole).
Detailed explanation-5: -When the right ventricle squeezes to pump blood to the lungs, the tricuspid valve closes. This keeps blood from flowing back into the right atrium. The right side of the heart (the right atrium and the right ventricle) gets oxygen-poor blood from the body and pumps it to the lungs.
