Detailed explanation-1: -After the absorbable particles are absorbed through the villi, the nutrients enter the blood vessels present below the villi. Blood transports the nutrients to the cell for the generation of energy or storage of nutrients.
Detailed explanation-2: -The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.
Detailed explanation-3: -Villi contain capillary beds, as well as lymphatic vessels called lacteals. Fatty acids absorbed from broken-down chyme pass into the lacteals. Other absorbed nutrients enter the bloodstream through the capillary beds and are taken directly to the liver, via the hepatic vein, for processing.
Detailed explanation-4: -The structure of the small intestine is designed for absorption of nutrients. The inside of the small intestine is lined with villi that absorb nutrients from the liquid mixture called chyme produced in the stomach from the food we eat.
Detailed explanation-5: -The digested food passes through the walls of the small intestine and is absorbed by the villi present on the inner wall of small intestine and reaches into the bloodstream.
