A) Stroke volume × heart rate.
B) Stroke volume/body surface area.
C) Body surface area × cardiac index.
D) Heart rate/stroke volume.

Cardiac Output

The volume of blood the heart pumps through the circulatory system in one minute.

Stroke Volume

The amount of blood pumped by the left ventricle of the heart in one contraction.

Heart Rate

The number of heart beats per minute, a vital sign indicating the health and fitness level of an individual.
