Normal Images of the Stomach

These are images of the normal stomach. The stomach has two parts. The upper part is called the fundus. It is where food enters from the esophagus and where it stays until it is ground into small fragments. The antrum is the grinder of the stomach. It is where food is churned back and forth until small spurts of liquid and particles of food are passed through the pylorus which is the name of the outlet valve of the stomach. Image 1 is a picture of the fundus or upper portion of the stomach. You see the endoscope has entered the stomach and then has made a U-turn to take the picture. Image 2 is the antrum with the pylorus in the distance. Image 3 is a close up of the pylorus which normally continuously opens and closes.
