Final answer:
Capsular hydrostatic pressure (CHP) is the pressure from fluid already in the glomerular (Bowman's) capsule and it promotes the filtration of substances into the glomerular capsule.
Step-by-step explanation:
Capsular hydrostatic pressure (CHP) refers to the pressure from fluid already in the glomerular (Bowman's) capsule. It is one of the factors that determines the net filtration pressure (NFP) in the kidneys. NFP is calculated by subtracting the sum of capsular hydrostatic pressure (CHP) and blood colloid osmotic pressure (BCOP) from the glomerular blood hydrostatic pressure (GBHP). In the filtration process, CHP promotes the movement of fluid and substances into the glomerular capsule.
