A 56-year-old man with an insufficient aortic valve is scheduled for surgery. Identify the chamber of the heart that the regurgitated blood most likely enter. Will the blood regurgitated primarily during systole or diastole?

Answerand Explanation:

The regurgitated blood will enter the left chamber of the heart. This is because as the patient's aotic valve is not working properly, it does not close properly, which allows a backflow of blood to occur towards the left chamber of the heart, as this chamber relaxes to be filled with blood pumped by the right camera.

As the regurgitated blood is a pumped blood, we can consider that it will happen, mainly during systole, which is the moment when the heart contracts to pump blood. This contraction will be made with the malfunction of the aortic valve which will cause blood regurgitation.
