Question

Cardiac output (CO) depends on two factors, which are __________.

Answer 1

Cardiac output depends on heart rate and stroke volume.

Step-by-step explanation:

Cardiac output (CO) depends on two factors, which are heart rate (HR) and stroke volume (SV). The heart rate is the number of contractions or beats per minute, while stroke volume is the amount of blood pumped by each ventricle with each heartbeat. These two factors work together to determine the amount of blood pumped by the heart in one minute.
