Kidney Function

The kidneys filter waste products from the blood and maintain the body's fluid balance.

Filtration

The process of separating the blood's waste products in the kidney.

Reabsorption

How do you calculate Net Filtration Pressure?

Net Filtration Pressure is calculated by subtracting the forces opposing filtration (Plasma-Colloid Osmotic Pressure + Bowman's Capsule Hydrostatic Pressure) from the force favoring filtration (Glomerular Capillary Blood Pressure).
