Which of these statements correctly describes cardiac output?
A)the volume of blood pumped by each ventricle during each contraction or beat
B)the volume of blood pumped by each ventricle per minute
C) stroke volume × SVR (systemic vascular resistance)
D) the volume of blood pumped by each atrium into ventricles

Question

Quizplus · Accepted Answer

Cardiac output refers to the amount of blood pumped by the heart per minute. It is calculated as the product of stroke volume (the volume of blood pumped out by each ventricle during each contraction) and heart rate (the number of contractions per minute). Therefore, statement B correctly describes cardiac output. Statements A, C, and D are incorrect.
