WebMay 13, 2010 · The normal exchange across the capillaries, which is determined by the transcapillary hydrostatic and colloid osmotic pressures, is the focus of the review by Levick and Michel 5 in this issue. The skin and skeletal muscle jointly contain around two-thirds of the extracellular fluid. WebCHP is the force that drives fluid out of capillaries and into the tissues. As fluid exits a capillary and moves into tissues, the hydrostatic pressure in the interstitial fluid correspondingly rises. This opposing hydrostatic pressure is called the interstitial fluid hydrostatic pressure (IFHP).

Image created at BYU-I Fall 2013 Continuous Capillaries WebAs the blood is pumped through this capillary network, gas exchange occurs. Although a small amount of the oxygen is able to dissolve directly into plasma from the alveoli, most of the oxygen is picked up by erythrocytes (red blood cells) and binds to a protein called hemoglobin, a process described later in this chapter.
