Final answer:
The capsular hydrostatic pressure is typically lower than the glomerular hydrostatic pressure, and an increase in capsular hydrostatic pressure will result in a decrease in the formation of filtrate in the kidneys.
Step-by-step explanation:
The capsular hydrostatic pressure is generally lower than the glomerular hydrostatic pressure; increases in capsular hydrostatic pressure decrease the formation of additional filtrate. When contemplating the pressures at play within the glomerulus of the kidneys, it is crucial to understand that the glomerular filtration occurs when the glomerular hydrostatic pressure, which is the pressure produced by the fluid in the glomerular capillaries, is higher than the luminal hydrostatic pressure in Bowman’s capsule.
Moreover, this process is counterbalanced by the osmotic pressure due to the presence of solutes such as proteins in the capillaries. Since these proteins cannot pass into Bowman's capsule, they create a colloid osmotic pressure within the glomerular capillary, contributing to the net filtration pressure that allows for the movement of water and small solutes into Bowman's capsule while keeping larger solutes within the bloodstream.
An increase in capsular hydrostatic pressure means that the pressure in Bowman’s capsule approaches that of the glomerular capillaries, thereby decreasing the net filtration pressure and reducing the formation of filtrate or urine.
