Expert Solution

Step 1

In cardiac physiology, Cardiac output refers to the amount of blood pumped out of each ventricle per unit time (per minute). In the case of a resting supine individual, cardiac output (often denoted as CO) averages about 5.5 L/min. Cardiac output sums the quantity of blood that is delivered to all the tissues across the body and hence, it is an important segment of cardiac physiology in explaining how efficient a heart can be to meet the body’s demand for the maintenance of adequate tissue perfusion. Any hindrance in the factors associated with cardiac output can majorly hamper cardiovascular interactions which can have significant effects on the concerned individual.
