a sack-like, muscular organ that is attached to the esophagus. Both chemical and mechanical digestion takes place in the stomach. When food enters the stomach, it is churned in a bath of acids and enzymes.
Fluids from the liver and pancreas dilute and further digest the"partly digested food". "Digested food", now in a liquid form, is absorbed into the bloodstream through the tiny blood vessels. The"indigestible food" goes on to the large intestine.
