Under which of these conditions will reabsorption occur
A)when inward-driving pressures exceed outward-driving pressures across the capillary wall
B)when outward-driving pressures exceed inward-driving pressures across the capillary wall
C)when the osmolarity of plasma is decreased in the venule end of the capillary
D)when the outward-driving pressures and the inward-driving pressures across the capillary wall are equal

Question

Quizplus · Accepted Answer

Reabsorption occurs when the inward-driving pressures exceed the outward-driving pressures across the capillary wall. This is because the pressure gradient favors the movement of fluid from the interstitial space back into the capillaries. In contrast, when outward-driving pressures exceed inward-driving pressures, fluid accumulation occurs in the interstitial space, leading to edema. Therefore, option A is the correct choice. Options B, C, and D are incorrect, as they do not describe the conditions that favor reabsorption.
