Question

The volume of blood pumped by each ventricle during a beat is known as systolic volume. If the systolic volume is multiplied by the number of beats per minute, the resulting value is the cardiac cost.

Cardiac cost = systolic volume * cardiac frequency

Which is the cardiac cost (volume of blood pumped by each ventricle in a minute) of an adult person in rest whose heart beats 72 times per minute and pumps 70 milliliters of blood in each contraction?

a. 3L/min
b. 5 L/min
c. 5 L/min
d. 50 L/min

Answer 1

5 L/min
