Human Heart: Structure and Working · NCERT Biology

During a cardiac cycle, the volume of blood pumped out by each ventricle per minute is called:

  1. Stroke volume
  2. Cardiac output
  3. End-diastolic volume
  4. Vital capacity
Show answer and explanation

Correct answer: Cardiac output

Cardiac output is defined as the volume of blood pumped out by each ventricle per minute. It is calculated by multiplying the stroke volume (approx. 70mL) by the heart rate (approx. 72 beats/min).
