Given below is a labeled diagram of the stomach to help you understand stomach anatomy. The stomach is divided into four parts. These include: Cardia refers to the section of the stomach that is located around the cardiac orifice. The lower esophageal sphincter lies at the junction where the esophagus meets the stomach.
The stomach is a J-shaped organ that digests food. It produces enzymes (substances that create chemical reactions) and acids (digestive juices). This mix of enzymes and digestive juices breaks down food so it can pass to your small intestine. Your stomach is part of the gastrointestinal (GI) tract.
The abdomen also contains the kidneys and spleen. Many important blood vessels travel through the abdomen, including the aorta, inferior vena cava, and dozens of their smaller branches. In the front, the abdomen is protected by a thin, tough layer of tissue called fascia.
