Question

Cardiac output is determined by multiplying stroke volume and heart rate. a. True b. False

Answer 1

Answer:

True

Explanation:

The amount of blood that the heart pumps per minute through the circulatory system is called the cardiac output.

Stroke volume is the amount of blood that pushed out of the ventricle in one contraction or one beat.

The cardiac output is calculated by multiplying the number of heartbeats per minute (heart rate) and the stroke volume.

Thus, cardiac output = Heart rate × Stroke volume. The value of cardiac output is expressed as litre/minute.
