Final answer:
The correct formula to calculate the net filtration pressure (NFP) is FP = GHP - (CsHP + BCOP), signifying the influence of hydrostatic and osmotic pressures in the filtration process of the kidneys.
Step-by-step explanation:
The formula that will allow you to calculate the net filtration pressure (NFP) is FP = GHP - (CsHP + BCOP). This is because NFP is determined by taking the glomerular blood hydrostatic pressure (GBHP), which is the same as GHP in the question, and then subtracting the sum of the capsular hydrostatic pressure (CHP, or CsHP as referred to in the question) and the blood colloid osmotic pressure (BCOP). Therefore, option B) FP = GHP - (CsHP + BCOP) is the correct formula to use when calculating this value.
It is important to understand that the NFP is affected by several pressures: The hydrostatic pressure in the glomerulus, the hydrostatic pressure in Bowman's capsule, and the osmotic pressure due to proteins in the blood. These pressures explain the filtration process in the kidneys, highlighting that slight changes can result in significant alterations in the rate at which filtrate is formed.
