A rat's stomach is roughly the shape of a C, or a circle with a semi-circle shaped indentation.

It has two sections - a thin walled non-glandular section called the forestomach (where the opening from the oesophagus is), and a thick walled glandular section known as the corpus. These are separated by a small fold of tissue known as the limiting ridge.

Food is stored in the forestomach, and the corpus is where digestive enzymes break food down.
