Describe the factors involved in capillary filtration and reabsorption. Include the following in your answer : blood osmotic pressure (BOP), blood hydrostatic pressure (BHP), interstitial fluid osmotic pressure (IOP), interstitial fluid hydrostatic pressure (IHP), arteriolar end, and venular end

What will be an ideal response?


In the arteriolar end of the capillary, the forces attempting to move fluid out of the capillary (BHP+IOP) are higher than the BOP+IHP, which are attempting to move fluid into the capillary. As fluid leaves the arteriolar end of the capillary, large solutes remain in the blood and increase the BOP as blood moves through the capillary. In the venular end, BOP+IHP is higher than BHP+IOP. As a result, there is a net movement of fluid into the capillary.
