Explanation:
Detailed explanation-1: -Tissue fluid is formed at the arteriole end of the capillary where there is large hydrostatic pressure from the left ventricle of the heart. This hydrostatic pressure within the capillary is greater than the pressure in the fluid surrounding the capillaries, therefore forcing the fluid out of the capillaries.
Detailed explanation-2: -Villi that line the walls of the small intestine absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system. Villi contain capillary beds, as well as lymphatic vessels called lacteals.
