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: -The mucosa that lines the small intestine is covered with fingerlike projections called villi. There are blood capillaries and special lymph capillaries, called lacteals, in the center of each villus. The blood capillaries absorb most nutrients, but the fats and fat-soluble vitamins are absorbed by the lacteals.
