Question

Quizplus · Accepted Answer

Venous return is the amount of blood that returns to the heart via the veins. It is important to maintain cardiac output, which is the total volume of blood pumped by the heart per minute. If venous return decreases, cardiac output will decrease, which can lead to decreased perfusion of the tissues and organs. Thus, option A is the best choice. Options B, C, and D are incorrect because they do not directly relate to the role of venous return in maintaining cardiac output.
