What is the stomach?
The stomach is in the upper abdomen. It is part of the gastrointestinal tract (the gut). It lies in the upper part
of the abdomen, just below the ribs. When we eat, food passes down the oesophagus (gullet) into the stomach.
The stomach makes acid which is not essential, but helps to digest food. The muscles in the wall
of the stomach contract to mix up the food with the acid.
Food then passes into the duodenum (the first part of the small intestine). Here food mixes with
enzymes (chemicals) which come from the pancreas and lining of the gut. The enzymes break down (digest)
the food.
Digested food is then absorbed into the body from the small intestine.
