Stomach
The stomach is part of the digestive
system.
It is a large muscular bag, which food collects in when we
eat. The food is mixed with gastric juice made by gland
cells in the stomach wall. This juice contains hydrochloric
acid and enzymes which digest
food.
The acid kills micro organisms in the food which we eat.
Partly digested food passes from the stomach into the small
intestine.
