Cardiac Output is Dependent on Both

Question

Cardiac output is dependent on both
A)heart rate and stroke volume.
B)stroke volume and systemic vascular resistance.
C)heart rate and systemic vascular resistance.
D)blood type and stroke volume.
E)blood pressure and heart rate

Accepted Answer

Cardiac output is the volume of blood pumped by the heart per unit of time. It is dependent on both heart rate, the number of times the heart beats per minute, and stroke volume, the amount of blood pumped out of the heart in each beat. Therefore, the correct choice is A, as it includes both heart rate and stroke volume.
