This shows an image through the wall of the body of the stomach at low power. You should be able to identify the three major layers seen here - the mucosa, submucosa and muscularis externa. The mucosa is full of gastric glands and pits, and there is a prominent layer of smooth muscle - the muscularis mucosa. The contraction of this muscle helps to expel the contents of the gastric glands. The muscularis externa layer has three layers of muscle.
One function of the stomach is to grind food into smaller particles and mix it with digestive juices so the food can be absorbed when it reaches the small intestine. The stomach normally empties its contents into the intestine at a controlled rate. The stomach has three types of contractions: There are rhythmic, 3 per minute, synchronized contractions in the lower part of the stomach, which create waves of food particles and juice which splash against a closed sphincter muscle (the pyloric sphincter) to grind the food into small particles.
