Explanation:
Detailed explanation-1: -Unlike other nutrients, fat cannot be absorbed directly into the blood from the gut because fat molecules are simply too large to be taken up by the tiny capillaries that line it; it would simply clog them up. Instead, it must be absorbed by another route – the lymphatic system.
Detailed explanation-2: -Fats are absorbed through the wall of the villi and enter the lacteal, tiny lymph vessels called lymph capillaries, where they form part of a fluid called chyle, a milky fluid consisting of lymph, fats, and free fatty acids. Lymphatic vessels then transport these fats into the bloodstream.
