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?

• solvent drag
• venous pooling
• cardiac suction
• venous return

Explanation:

To solve this, we analyze each option:

• Solvent drag: Involves movement of solutes with solvent, not blood accumulation in limbs.
• Venous pooling: Defined as blood accumulation in limbs when venous pressure can't overcome blood weight to drive it upward, matching the description.
• Cardiac suction: Related to heart's ability to draw blood, not limb blood pooling.
• Venous return: Is the blood flow back to heart, not accumulation in limbs.

Answer:

B. Venous pooling
