IMMUNOLOGY

Detailed explanation-1: -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. The lymph in the lacteals has a milky appearance due to its high fat content and is called chyle.

Detailed explanation-2: -Special lymphatic capillaries called lacteals exist in the small intestine to contribute to the absorption of dietary fats.

Detailed explanation-3: -The resulting mixture of lymphatic fluid and fats – a milky-white substance known as ‘chyle’ – is carried through the lymphatic network and into the largest of the lymphatic vessels – the thoracic duct and thenceforth directly into the heart.

Detailed explanation-4: -A lacteal is a blunt‐ended, long, tube‐like lymphatic vessel located in the center of each intestinal villus that provides a unique route for drainage of absorbed lipids from the small intestine.

Detailed explanation-5: -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.
