Stomach

The stomach is a hollow organ in the upper part of your abdomen that plays a crucial role in digestion. Shaped like a J, it connects the esophagus to the small intestine. When you eat, food travels down the esophagus and enters the stomach through an opening called the lower esophageal sphincter. Once inside, the stomach uses its muscular walls to mix the food with digestive juices, breaking it down into smaller pieces.

The stomach's acidic environment helps to kill bacteria and digest proteins. It produces a substance called gastric juice, which contains hydrochloric acid and enzymes that further aid in breaking down the food. After this initial digestion, the semi-liquid food, now called chyme, gradually moves into the small intestine where nutrient absorption begins.

Overall, the stomach is a vital part of your digestive system, helping you process the food you eat into nutrients your body can use.
