In the villi of the small intestine, nutrients from digested food, such as amino acids, monosaccharides, and fatty acids, are absorbed into the central vessel known as the lacteal. The lacteal primarily absorbs dietary fats and fat-soluble vitamins, while the surrounding capillaries absorb water-soluble nutrients. This absorption process is crucial for delivering essential nutrients into the bloodstream for use by the body.
Villi (Sing. Villus)
lacteal
It is where food molecules/ nutrients are absorbed into the blood.
Food molecules (glucose,amino acids and some glycerol and fatty acid), minerals (calcium,iron,etc) and vitamins. Most fat are absorbed in a lymph vessel found underneath the capillaries called the lacteal
Every villus has a network of capillaries and a lacteal.
Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals and the lymphatic system are used to absorb fats.
fats, then transport fats to the venous circulation
pl. of Villus., of Villus
The noun 'villi' is the plural form of the singular noun 'villus'.
The central opening of a vessel is called the lumen. It is the hollow space within the vessel that allows for the passage of fluids, such as blood in blood vessels or sap in plant vessels.
