Quizplus · Accepted Answer

Urinary output does not directly affect venous return as it is a function of the kidneys and relates to fluid balance and waste excretion from the body, not the circulatory system. The other options (A, B, and C) all play important roles in aiding venous return. The activity of skeletal muscles helps to compress veins and promote blood flow back towards the heart, venous valves prevent backflow of blood, and pressure changes in the thorax (such as during breathing and changes in body position) help to create a pressure gradient that facilitates venous return.
