Summary Introduction
Introduction:
The process of urine formation occurs in the renal corpuscle via glomerular capillaries. While the filtrate leaves the glomerular capillary, from there, the urine is received by Bowman’s capsule. There are three forces that influence the rate of filtration, which are the hydrostatic pressure, the fluid pressure in Bowman’s capsule, and the osmotic force caused by the protein difference. Hydrostatic pressure enhances the rate of filtration while the other two limit it.
