There are also two opposing oncotic pressures influencing fluid exchange: capillary plasma oncotic pressure (πC) and tissue (interstitial) oncotic pressure (πi).

The average capillary is only about 1 mm long. The capillary beds are the region of exchange of materials with the tissues. O2 and nutrients are supplied to the cells, and CO2 and other waste products are taken away.

As blood enters capillaries, molecules small enough to cross through the endothelial cells follow their concentration gradients in or out of the bloodstream. Osmotic pressure of the blood (blood colloid osmotic pressure) causes most of the water to move back in by osmosis by the time the blood enters the venule...

Exchange of solutes between the blood and surrounding tissues only occurs across the endothelial walls of the capillaries. ... At the arterial end of a capillary bed, the relatively high blood pressure (enough to override the osmotic pressure driving fluid into the blood) drives additional fluid out of the blood.

Evolving ideas about osmosis and capillary fluid exchange 1 ... Fluid exchange across the capillary endothelium is influenced, in part, by colloidal proteins in the plasma. The role of the proteins in capillary fluid exchange must be reinterpreted based on Hulett's view, the only valid view of osmosis.—Hammel, H. T.
