Bowman’s capsule hydrostatic pressure

Definition

Bowman's capsule hydrostatic pressure is the pressure exerted by fluid in the Bowman's capsule against the filtrate from the glomerulus. This pressure plays a crucial role in the regulation of glomerular filtration rate (GFR).

5 Must Know Facts For Your Next Test

1. Bowman's capsule hydrostatic pressure usually opposes glomerular filtration.
2. An increase in Bowman's capsule hydrostatic pressure can lead to a decrease in GFR.
3. Conditions like urinary tract obstructions can raise Bowman's capsule hydrostatic pressure.
4. This pressure works alongside glomerular capillary hydrostatic pressure and blood colloid osmotic pressure in determining net filtration.
5. Maintaining a balanced Bowman's capsule hydrostatic pressure is essential for proper kidney function.
