With respect to the hydrostatic pressure and osmotic pressure, which one is greater at the capillary end, and which one is greater at the venous end?
Expert Solution
Step 1
The exchange of material in the capillary is determined by the hydrostatic pressure and oncotic pressure. Hydrostatic pressure refers to the pressure produced by the fluid (blood or interstitial fluid) on the capillary walls. While oncotic pressure (a type of osmotic pressure) refers to the pressure exerted by the proteins in the blood plasma.
