WebJan 17, 2024 · Capillary exchange refers to the exchange of material from the blood into the tissues in the capillary. There are three mechanisms that facilitate capillary exchange: diffusion, transcytosis and bulk flow. Capillary dynamics are controlled by the four Starling forces. Oncotic pressure is a form of osmotic pressure exerted by proteins either in ... WebNFP changes at different points in a capillary bed (Figure 6.8.1). Close to the arterial end of the capillary, it is approximately 10 mm Hg, because the CHP of 35 mm Hg minus the BCOP of 25 mm Hg equals 10 mm Hg.
