What is the function of lacteals?

• A. Filter bacteria from the blood
• B. Absorb fats and nutrients from the small intestine
• C. Produce red blood cells
• D. Pump lymph to heart

Answer: (B)

Lacteals are specialized lymphatic capillaries tucked into the villi of the small intestine. Their main job is to absorb dietary fats that have been broken down and packaged into chylomicrons. These lipid particles are too large to fit into blood capillaries, so they enter the lymphatic system through the lacteals and are transported as chyle, eventually reaching the bloodstream via the thoracic duct. In addition to fats, they contribute to the uptake of fat-soluble vitamins. So, the function of lacteals is to absorb fats and related lipids from the small intestine.
