Once filtration begins, the pressure gradually drops to 18mm Hg, but there is also a pressure created due to the presence of colloidal proteins in the blood. If the pressure is high, this aids in increased uptake of water into the capillary. This ranges to about 25 mmHg. claudia fogertyWebfiltration occurs when a. the filtrate passes from peritubule capillaries to nephron loop b. blood fluids leave afferent arteriole and enter bowmans capsule c. blood fluids leave … claudia freyth schwelm
