The stomach wall - image description

On the left of the page, the illustration shows the gullet (oesophagus) coming down from the top of the page into the stomach. The small intestine runs from the bottom of the stomach to the bottom of the page. On the right of the illustration is an enlarged cross section of the stomach wall.  This shows the four layers of the stomach wall. The mucosa is to the right, on the inside of the stomach. This is shown as a ridged layer made up of small egg-shaped glands that produce enzymes.  To the right of the mucosa is the submucosa, and to the right of this, the muscle layer. Furthest to the right is the outer layer called the serosa. The three outer layers are shown in different colours and textures.
