What does the lymphatic system absorb from the intestinal tract?

Lipids Water Proteins Vitamins

Correct Answer:

Lipids

Explanation:

The key idea is how fats are absorbed after a meal. Fats in the intestinal lining are reassembled into triglycerides and packaged into chylomicrons, which enter the lacteals—special lymphatic vessels in the intestinal villi. From there, these lipid-containing particles travel through the lymphatic system before entering the bloodstream. This is why lipids are the correct answer: the lymphatic system is the route for absorbing dietary fats. In contrast, water and most proteins move into blood capillaries for transport via the portal circulation, and vitamins follow their own routes, often with fats, but the primary absorber among the options is lipids.
