The figure аbоve summаrizes the hydrоstаtic and оsmotic pressures that favor or oppose glomerular filtration in a healthy person. Imagine a patient is diagnosed with a severe urinary tract infection which has resulted in low systemic BP (hypotension). This has resulted in the hydrostatic pressure of the glomerular capillary (HPc) dropping to 35 mmHg. The osmotic pressure of the glomerular capillary (OPc) is 15 mmHg, and the hydrostatic pressure of the interstitial fluid in the Bowman’s space (HPif) is 20 mmHg. What is the glomerular filtration rate and what effect would it have on filtration?
