The stomach is a muscular, hollow organ in the digestive system that functions as a reservoir for food. It is responsible for mechanically breaking down food and mixing it with gastric juices to form chyme, a semi-liquid substance. The stomach is divided into four main regions: the cardia, fundus, body, and pylorus. It has a highly elastic structure, allowing it to expand to accommodate food and liquids. Explore the diagram of stomach parts, detailing the structure and function of each section, from the esophagus to the intestines, for better understanding of digestion. See a medical illustration of the abdominal area and its organs, such as the stomach , liver, and intestines.
