Absorption is the process of movement of nutrient molecules across the villi of the small intestine into the blood. Then, they are made into parts of cells and tissues in the body, and that process is called assimilation.
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.
