Question

Quizplus · Accepted Answer

Osmosis is the process by which water moves across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this context, a higher protein concentration in the distal portion of capillaries would draw water into them through osmosis, as water moves towards the higher concentration of solutes (proteins) to balance the concentration on both sides of the capillary walls.
