<h3><u>Answer;</u></h3>
Preload, afterload, and contractility
<h3><u>Explanation;</u></h3>
- Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload.
- Preload is the initial stretching of the cardiac myocytes or muscle cells prior to contraction. Afterload is the force or load against which the heart has to contract to eject the blood.
- Contractility is the intrinsic strength of the cardiac muscle independent of preload, but a change in preload will affect the force of contraction.
