The stomach is a muscular organ located between the esophagus and the small intestine. Its main function is to receive food from the esophagus, break it down into smaller pieces, and mix it with digestive juices before sending it to the small intestine for further digestion and absorption. The stomach has several important structures and features that contribute to its function, including the gastric glands, gastric juice, and the various layers of smooth muscle that allow it to contract and churn the food.
