Question

What would happen if the capsular hydrostatic pressure were increased above normal?

Select one:

A. Net filtration would decrease.

B. Filtration would increase in proportion to the increase in capsular pressure.

C. Net filtration would increase above normal.

D. Capsular osmotic pressure would compensate so that filtration would not change.

Answer 1

What would happen if the capsular hydrostatic pressure were increased above normal?

Answer: Net filtration would decrease.

Capsular hydrostatic pressure (CHP) — The hydrostatic force that is the mechanical pressure exerted on the plasma filtrate by the elastic recoil of the glomerular capsule, which helps to drive water and dissolved solutes from the plasma filtrate back into the glomerulus capillaries; that is the primary force that slows down the rate of filtrate production in the renal corpuscle.

Net filtration pressure (NFP) = glomerular blood hydrostatic pressure – [capsular hydrostatic pressure + blood colloid osmotic pressure .
