Plasma is forced out of the capillaries and forced back in due to interactions of hydrostatic pressure. The proportion of interstitial fluid that is returned to the circulatory system by osmosis is about 90% of the former plasma; with about 10% accumulating as overfill. The excess interstitial fluid is collected by the lymphatic system by diffusion into lymph capillaries, and is processed by lymph nodes prior to being returned to the circulatory system.
