WebMay 15, 2024 · A filtrate depleted of protein passes by ultrafiltration through the lung capillaries, thereby creating a higher COP in plasma that may partly counterbalance the elevated hydrostatic pressure accumulated. The lymphatic system of the lungs provides a safety mechanism to remove fluid from the air spaces until this mechanism is saturated. [5] WebJan 17, 2024 · oncotic pressure: A form of osmotic pressure exerted by proteins in a fluid that usually tends to pull water into the circulatory system. Capillary exchange refers to the exchange of material between the blood and tissues in the capillaries. There are three mechanisms that facilitate capillary exchange: diffusion, transcytosis, and bulk flow.
