RRB Group D (Level-1 posts) 2022 · Question 317 of 598

Which of the following events takes place during diastole in the human heart?

  1. ABlood leaves the ventricle
  2. BBlood enters the aorta
  3. CBlood enters the ventricleCorrect
  4. DBlood enters the lungs

Answer: C. Blood enters the ventricle

Explanation

Diastole is the phase of the cardiac cycle when the heart muscles relax after contraction, allowing the chambers to fill with blood. During diastole, the ventricles are relaxed, and blood flows from the atria into the ventricles as the atrioventricular (AV) valves (the tricuspid and mitral valves) open. Thus, the correct answer is Blood enters the ventricle.
