उत्तर
- Cardiac output is the volume of blood that the heart pumps out in a minute. It is computed by multiplying heart rate (the number of beats per minute) by stroke volume, which is the amount of blood pumped by each ventricle per minute.
- A healthy person's heart beats 72 times per minute, pumping out roughly 70 millilitres of blood with each beat. As a result, the average cardiac output is five litres, or 5000 mL.
