Explanation:

Cardiac output is defined as the product of stroke volume (the amount of blood pumped out by the heart with each beat) and heart rate (the number of times the heart beats per minute). Venous return refers to the amount of blood returning to the heart. Preload is the degree of stretch of the cardiac muscle fibers at the end of diastole. Afterload is the resistance against which the heart pumps.

Answer:

cardiac output
