Question

multiple choice question
which term refers to the accumulation of blood in the limbs that occurs when venous pressure is not high enough to overcome the weight of the blood and drive it upward?

venous return
solvent drag
cardiac suction
venous pooling

Explanation:

To solve this, we analyze each option:

• Venous return: The flow of blood back to the heart, not accumulation in limbs.
• Solvent drag: Movement of solutes with solvent (like in capillaries), not related to blood accumulation in limbs due to venous pressure.
• Cardiac suction: The heart's ability to draw blood, not about blood pooling in limbs.
• Venous pooling: Defined as blood accumulating in limbs when venous pressure can't overcome blood's weight to drive it upward. This matches the description.

Answer:

D. Venous pooling
