Layers of the Stomach. Stomach has gastric pits, which has gastric glands that secrete acids. The mucosa forms folds called rugae that look like wrinkles and flatten as your stomach gets full. Here's more about the layers of the stomach. 1. Mucosa. This is the innermost layer of the stomach.
Surrounding the mucosa is the submucosa layer of the stomach. The submucosa is made up of various connective tissues, blood vessels, and nerves. Connective tissues support the tissues of the mucosa and connect it to the muscularis layer. The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances. Muscularis. The muscularis layer of the stomach surrounds the submucosa and makes up a large amount of the stomachâs mass. The muscularis is made of 3 layers of smooth muscle tissue arranged with its fibers running in 3 different directions. These layers of smooth muscle allow the stomach to contract to mix and propel food through the digestive tract. Serosa
