Question

During ventricular diastole

• A. The auricles relax
• B. The heart contracts
• C. The heart pumps blood
• D. The ventricles relax

Answer 1

The correct option is D The ventricles relax

Ventricular diastole is the period during which the ventricles relax. It is the time when the blood flows in the ventricles. The aortic valve and pulmonary valve remain closed to maintain the pressure inside the ventricles while the atrioventricular mitral and tricuspid valves remain open to allow the blood flow from atria to the ventricle.

So, the correct answer is option D.
