Solution
To answer the question, let's break down the components involved in the filtration process in the kidneys:
-
Glomerular Hydrostatic Pressure (GHP): This is the blood pressure within the glomerular capillaries that pushes water and solutes out of the blood and into the Bowman’s capsule.
-
Bowman’s Capsule Hydrostatic Pressure (CHP): This is the pressure exerted by the fluid already in the Bowman’s capsule. It opposes the GHP.
-
Blood Colloid Osmotic Pressure (BCOP): This is the osmotic pressure due to proteins in the blood that tends to pull water back into the capillaries.
-
Net Filtration Pressure (NFP): This is the overall pressure driving fluid out of the glomerulus and into the Bowman’s capsule. It is calculated as:
Given that the Bowman’s capsule hydrostatic pressure (CHP) is increased above normal, let's analyze the impact on the Net Filtration Pressure (NFP):
- An increase in CHP would mean that the opposing force to GHP is greater.
- Since NFP is calculated by subtracting CHP (along with BCOP) from GHP, an increase in CHP would result in a decrease in NFP.
Therefore, the correct answer is:
b. Net filtration pressure would decrease below normal
