Lacteals
Lacteals
Lacteals (pronunciation: /ˈlæk.ti.əl/) are specialized lymphatic vessels present in the villi of the small intestine. They play a crucial role in the absorption of dietary lipids and fat-soluble vitamins.
Etymology
The term 'lacteal' is derived from the Latin word 'lacteus', which means 'milky'. This is due to the milky appearance of the lymph, or chyle, that is transported by the lacteals after a fatty meal.
Function
Lacteals absorb digested fats and fat-soluble vitamins from the small intestine and transport them to the bloodstream. This process is essential for the body's overall nutrition and energy production.
Structure
Lacteals are part of the larger lymphatic system. They are located in the core of each intestinal villus and are surrounded by a network of capillaries. The absorbed fats and vitamins are converted into chylomicrons and then transported by the lacteals to the bloodstream.
