In the joint diastole state, which of these events do not occur?a)All ...
Explanation:
Joint Diastole State:
In the joint diastole state, the heart is in a period of relaxation where both atria and ventricles are in diastole. During this phase, the following events occur:
- All four chambers are relaxed: Both atria and ventricles are relaxed to allow blood to flow into the atria from the veins.
- Blood from the pulmonary vein flows into the right atrium: This blood is oxygenated and flows into the right atrium from the pulmonary vein.
- Both tricuspid and bicuspid valves are closed: The tricuspid valve (between the right atrium and ventricle) and the bicuspid valve (between the left atrium and ventricle) are closed to prevent backflow of blood.
- Both semilunar valves are closed: The semilunar valves, including the pulmonary valve and aortic valve, are also closed during diastole to prevent blood from flowing back into the ventricles.
Why blood from the pulmonary vein does not flow into the right atrium:
During the joint diastole state, blood from the pulmonary vein does not flow into the right atrium. This is because the tricuspid valve is closed, preventing the backflow of blood into the right atrium. The blood instead remains in the pulmonary circulation until the next phase of the cardiac cycle.
Therefore, in the joint diastole state, all four chambers are relaxed, both tricuspid and bicuspid valves are closed, and both semilunar valves are closed. However, blood from the pulmonary vein does not flow into the right atrium during this phase.
