A kidney dialysis machine removes solutes from the blood by means of ____.
A)pinocytosis
B)exocytosis
C)diffusion
D)active transport
E)bulk flow

Question

Quizplus · Accepted Answer

A kidney dialysis machine works by using diffusion to remove solutes from the blood. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, and this process is used in dialysis to remove waste products and excess fluid from the blood. Unlike active transport, which requires energy, diffusion occurs naturally and does not require additional resources. Neither pinocytosis nor exocytosis are involved in kidney dialysis, and while bulk flow may occur in some physiological processes, it is not the primary mechanism by which solutes are removed in dialysis.
