The submucosa layer of the gi tract wall contains glands, blood vessels, and nerves, whereas the serosa layer is the outermost layer that protects the GI tract.

The gastro intestinal tract (GI) is a series of hollow organs that extend from the mouth to the anus. The hollow organs of the GI tract include the mouth, esophagus, stomach, small intestine, large intestine, and anus. The submucosa layer of the GI tract wall contains blood vessels, glands, nerves, and lymphatic vessels. The serosa layer is the outermost layer of the GI tract. The serosa layer is made up of areolar connective tissue that protects the GI tract.
