Which of the following describes the function of lacteals?

Lacteals play a crucial role in the digestive system, specifically in the absorption of dietary fats. These specialized lymphatic vessels are found in the villi of the small intestine. When fats are consumed, they are broken down into smaller components, including fatty acids and glycerol. In the intestine, these components are reassembled into triglycerides and packaged into chylomicrons, which are then taken up by the lacteals.

Once inside the lacteals, the chylomicrons enter the lymphatic system and eventually make their way into the bloodstream, where they can be transported to various tissues for energy or storage. This process is vital because fats are a major source of energy and are necessary for the absorption of fat-soluble vitamins (A, D, E, and K). Therefore, the primary function of lacteals is to facilitate fat absorption, which is why this answer is appropriate.
