The main force that promotes filtration in a nephron is:
A)glomerular colloid osmotic pressure (GCOP).
B)capsular hydrostatic pressure (CHP).
C)glomerular hydrostatic pressure (GHP).
D)colloid osmotic pressure (COP).

Question

Quizplus · Accepted Answer

Filtration in a nephron is promoted by the glomerular hydrostatic pressure (GHP) which is the pressure exerted by the blood in the glomerular capillaries. This pressure is higher than the capsular hydrostatic pressure (CHP) and the glomerular colloid osmotic pressure (GCOP) which promote reabsorption of fluids from the filtrate back into the bloodstream. Colloid osmotic pressure (COP) refers to the pressure exerted by the proteins in the plasma and is not directly involved in promoting filtration in a nephron.
