•Capillary exchange of nutrients, gases, and metabolic wastes occurs between theblood and interstitial space through diffusion.•Hydrostatic pressure (HP) is the force of a fluid against a membrane.•Colloid osmotic pressure (OP), the force opposing hydrostatic pressure, is created bythe presence of large, nondiffusible molecules that are prevented from moving throughthe capillary membrane.•Fluids will leave the capillaries if net HP exceeds net OP, but fluids will enter thecapillaries if net OP exceeds net HP.CH 16 Blood1. List the functions of blood.
