Cells and transport proteins are physically prevented from passing through the filtration membrane.This has the following effect on filtration.
A) decreased osmotic pressure in the filtrate that increases the amount of filtration
B) increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration
C) neutral change in osmotic pressure with no effect on filtration
D) increased osmotic pressure in the filtrate the draws plasma through the membrane

Question

Quizplus · Accepted Answer

Cells and transport proteins are physically prevented from passing through the filtration membrane. This means that the molecules that are filtered are those that are small enough to pass through the membrane, such as water and small solutes. As a result, the osmotic pressure in the glomerular capillaries increases, which reduces the amount of filtration that occurs. Therefore, the best choice is B.
