Question

Quizplus · Accepted Answer

This process of "pushing" fluids across a membrane in the kidneys is known as filtration. In this process, the blood pressure forces water and small solutes across the filtration membrane, leaving larger solutes, such as blood cells and proteins, behind in the blood vessels. Hence, the best choice is D, filtration.
