Layers of GI Tissue The GI tract is composed of four layers. Each layer has different tissues and functions. From the inside out they are called: mucosa, submucosa, muscularis, and serosa. The mucosa is the innermost layer, and functions in absorption and secretion.
What is stomach lining called?
The mucosa (mucous membrane) is the inner lining of the stomach. When the stomach is empty the mucosa has a ridged appearance. These ridges (rugae) flatten out as the stomach fills with food. The next layer that covers the mucosa is the submucosa.

Layers of Stomach Wall Layers of the stomach wall, among others, include serosa, muscularis, submucosa, mucosa. The three layers of smooth muscle consist of the outer longitudinal, the middle circular, and the inner oblique muscles.
Which organ system is the stomach part of?
