NEET BIOLOGY

Detailed explanation-1: -A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine.

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.

Detailed explanation-3: -Lacteals are the lymphatic capillaries which absorb fats and fat-soluble vitamins in the villi of the small intestine. Owing to its larger diameter than blood capillaries, fat molecules are absorbed by lacteals from the intestine.

Detailed explanation-4: -Answer and Explanation: The end products of lipid digestion are absorbed into lacteals. Lipid digestion is a process that occurs with the help of lipase. The lipid digestion occurs inside the intestine and then the digested lipid is absorbed with the help of bile salts.

Detailed explanation-5: -The initial lymphatics in the villi of the small intestine, called lacteals, collect fluids, electrolytes and proteins from their surrounding interstitial space. Importantly, in addition the lacteals also transport lipids from the interstitium of the intestinal villi into the lymph.
