Human stomach anatomy. The abdomen commonly called the belly is the body space between the thorax chest and pelvis. The human stomach is subdivided into four regions. As food reaches the end of the esophagus it enters the stomach through a muscular valve called the lower esophageal sphincter.

At the level of the pelvic bones the abdomen. It is an expanded section of the digestive tube between the esophagus and small intestine. The stomach secretes acid and enzymes that digest food.

The body or intermediate region the central and largest portion. The antrum the lowermost somewhat funnel shaped portion of the stomach. The stomach is an organ of the digestive system.

Ridges of muscle tissue called rugae line the stomach. When that muscle doesnt relax properly it feels like it is difficult to swallow. In simple terms the stomach is a kind of digestive sac.

And the pylorus a narrowing where the stomach joins the small intestine. The diaphragm forms the upper surface of the abdomen. Picture of the stomach.

The fundus an expanded area curving up above the cardiac opening the opening from the stomach into the esophagus. It is a continuation of the esophagus and receives our churned food from it. Therefore the stomach serves as a kind of connection between the esophagus and the small intestine and is a definite pit stop along our alimentary canal.

On the opposite end of the stomach the pyloric sphincter regulates the speed at which food moves down to the small intestine.
