Final answer:
Fat-soluble vitamins and dietary lipids are absorbed into the lymphatic system before entering the blood. They are transported in the form of chylomicrons through the network of lymphatic vessels after being processed by the enterocytes in the small intestine.
Step-by-step explanation:
The nutrients that are absorbed into the lymphatic system before entering the blood are the fat-soluble vitamins and dietary lipids. Unlike water-soluble vitamins that can be directly absorbed into the bloodstream, fat-soluble vitamins, along with lipids, are absorbed through the mucosa of the intestinal villi. This process is facilitated by the formation of micelles with the help of bile salts and lecithin, which help carry fat particles to the surface of enterocytes, where they diffuse across the membrane and are repackaged into chylomicrons.
