Why does blood pressure in the aorta drop during the diastole phase of the cardiac cycle?

💡 Explanation

Blood pressure in the aorta drops during diastole because of the windkessel effect; the aorta and large arteries stretch during systole and then recoil elastically during diastole, maintaining pressure. Therefore, the elastic recoil of the aorta is the answer, rather than valve failure or ventricular issues.
