Higher hydrostatic pressure at the arteriole end of capillaries forces plasma out, while lower pressure at the venule end allows tissue fluid into the blood.
In capillaries, higher hydrostatic pressure at the arteriole end forces fluids and nutrients out, while lower pressure at the venule end allows waste products to enter the blood.

| Back | higher hydrostatic (vs. blood osmotic) pressure at arteriole end of capillary forces bloodstream oxygen/nutrients into tissue fluid, lower pressure at venule end allows tissue's CO2/urea into bloodstream |
