The energy for the process of filtration is provided by:
A)the ATP within cells
B)the free energy of molecules
C)blood pressure in capillaries
D)a concentration gradient of dissolved materials

Question

Quizplus · Accepted Answer

Filtration in the kidneys is primarily driven by blood pressure in the glomerular capillaries. This pressure forces water and small solutes through the filtration membrane and into the Bowman's capsule, while larger molecules such as proteins and blood cells are retained in the bloodstream. The energy for this process comes from the pressure gradient created by the heart's pumping action.
