Question

The volume of blood discharged from the ventricle in a minute heartbeat is known as ________.

Select one:
a. cardiac cycle
b. stroke volume
c. minute cardiac volume
d. cardiac output

Answer 1

Cardiac output is the volume of blood pumped by the heart per minute, calculated by multiplying stroke volume by heart rate. The correct term that describes this measure is 'cardiac output'.

Step-by-step explanation:

The volume of blood discharged from the ventricle in a minute heart beat is known as cardiac output. Cardiac output (CO) is the measurement of the amount of blood each ventricle pumps out in one minute. It is calculated by multiplying the stroke volume (SV), which is the amount of blood pumped by a ventricle during a single heartbeat, by the heart rate (HR), the number of heart beats per minute. Therefore, the correct answer to the question is 'd. cardiac output'.
