A lymphatic capillary that picks up dietary lipids in the small intestine is called a(n):

• A. Cisterna chyli
• B. Lacteal
• C. Afferent lymphatic vessel
• D. Trabeculum
• E. Efferent lymphatic vessel

Answer: (B)

The correct response is the lacteal, which is a specialized lymphatic capillary located in the villi of the small intestine. Its primary function is to absorb dietary lipids, particularly long-chain fatty acids and fat-soluble vitamins, from the digestive tract. The structure of lacteals allows them to effectively pick up these lipids, which are then transported through the lymphatic system before entering the bloodstream. After fats are emulsified and digested, they enter the intestinal cells and are packaged into chylomicrons, which are too large to enter blood capillaries directly. Instead, they are taken up by the lacteals, making them essential in the process of fat absorption. This specialized function distinguishes lacteals from other lymphatic structures, emphasizing their role in lipid transport within the body. The other choices refer to different components of the lymphatic system or anatomical structures but do not specifically relate to the absorption of dietary lipids in the small intestine.
