NEET BIOLOGY

Detailed explanation-1: -These nutrients can then enter the lymphatic system before they eventually end up in the bloodstream later in the process. Therefore, the function of the lacteals in the small intestine is given by answer choice (B), to absorb fats and fat-soluble substances into the lymphatic system.

Detailed explanation-2: -The function of the lacteal in the small intestine: During the process of digestion, the lacteals absorb large molecules of fats and lipids from the small intestine which gives them a milky-white appearance. They act as a passage to transport the contents in the form of lipoproteins into the lymphatic system.

Detailed explanation-3: -The small intestine consists of hair-like minor projections called villi. These villi are comprised of capillaries as well as lymphatic vessels called lacteals. Lacteals are majorly involved in the absorption of fats and fat-soluble vitamins. The fat-soluble vitamins are vitamin A, D, E and K.

Detailed explanation-4: -Villi contain capillary beds, as well as lymphatic vessels called lacteals. Fatty acids absorbed from broken-down chyme pass into the lacteals. Other absorbed nutrients enter the bloodstream through the capillary beds and are taken directly to the liver, via the hepatic vein, for processing.

Detailed explanation-5: -The lacteal is surrounded by the capillaries. Digested nutrients pass into the blood vessels in the wall of the intestine through a process of diffusion.
