Question about kidneys.
Let Pc; glomerular capillary hydrostatic pressure Pbc; Bowman's sac hydrostatic pressure πc; glomerular capillary colloid osmotic pressure πbc; Bowman's sac colloid osmotic pressure ⊿P:=Pc-Pc .
My textbook states that ⊿Pc can be considered constant within the glomerular capillaries.
Since the capillaries within the glomerulus are very long and bent, it seems likely that friction would cause pressure impairment, but why can ΔPc be considered constant?
