Glands lining the stomach secrete hydrochloric acid that dissolves food particles and protein-digesting enzymes, called pepsin. Final stages of digestion and most of the nutrient absorption occurs in next portion of the tract: the small intestine. The small intestine is divided into 3 segments-duodenum, jejunum, and ileum. The pancreas is a gland located behind the stomach.
The process is carried out by enzymes in the stomach and small intestines.

Absorption is the entrance of the digested food (now called nutrients) into the body.
