What is the net filtration pressure determined by in the glomerulus?
Understand the Problem
The question is asking what factors contribute to the net filtration pressure in the glomerulus, which is a key concept in renal physiology. Specifically, it is looking for the correct formula or method to calculate this pressure based on given options.
Answer
NFP = GBHP - (CHP + BCOP).
The net filtration pressure (NFP) in the glomerulus is determined by subtracting the sum of capsular hydrostatic pressure (CHP) and blood colloid osmotic pressure (BCOP) from glomerular blood hydrostatic pressure (GBHP).
Answer for screen readers
The net filtration pressure (NFP) in the glomerulus is determined by subtracting the sum of capsular hydrostatic pressure (CHP) and blood colloid osmotic pressure (BCOP) from glomerular blood hydrostatic pressure (GBHP).
More Information
Net filtration pressure is essential in determining the glomerular filtration rate (GFR), which is important for kidney function. It results from balancing pressures that promote and oppose filtration.
Tips
A common mistake is misunderstanding which pressures oppose and which promote filtration, leading to errors in calculating net filtration pressure.
