Final answer:
A. Lacteals
Lacteals are specialized lymphatic capillaries in the small intestine that absorb dietary fats and transport them as chyle to the bloodstream.
Step-by-step explanation:
The specialized lymphatic capillaries known as lacteals absorb dietary fats in the small intestine. In every villus of the small intestine, there is a dense network of blood capillaries and these specialized lymphatic vessels called lacteals. While the blood capillaries mainly absorb nutrients like simple sugars and amino acids, the lacteals are responsible for absorbing fatty acids and fat-soluble vitamins (A, D, E, K) from the digestion of lipids. These fats enter the lacteals to form a milky fluid known as chyle, which is then transported through the lymphatic system to the bloodstream. This process is crucial for the transportation of dietary lipids and lipid-soluble vitamins to the bloodstream, allowing the body to make use of these vital nutrients.
