and shrinks when empty, it is full of stomach
acid which partially digests food, after the food
is digested, it passes into the small Intestine.
Small intestine
Partially digested food is passed into the
small intestine so that it can be further
digested as well as absorb nutrients from
the food. The small intestine consists of the
Duodenum, Jejunum and Ileum.
