Explanation: 

Detailed explanation-1: -Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Detailed explanation-2: -Chyme passes from the stomach into the duodenum. There it mixes with bile and pancreatic juices that further break down nutrients. Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients.

Detailed explanation-3: -Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface. The epithelial cells of the villi transport nutrients such as carbohydrates and amino acids from the lumen of the intestine into these capillaries and lacteals (lipids).
