Q. Cardiac output is
A) Stroke volume $\times$ Heart rate = 72 mL/m
B) Stroke volume $\times$ Heart rate = 5 L/m
C) Stroke volume $\times$ Heart rate = 500 mL
D) Stroke volume $\times$ Heart rate = 3 L/m
Explanation
Stroke volume = 70 mL/beat Heart rate = 72 beat/minute Cardiac output = Stroke volume $\times$ Heart rate $= 70 \times 72 = 5040$ mL/minute or approximately 5 L/min
