the stomach
After the food passes through the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. Once in the stomach, the food undergoes further digestion. The stomach secretes gastric juices, including hydrochloric acid and enzymes, which break down the food into smaller particles. This process is known as gastric digestion. The partially digested food, called chyme, then moves into the small intestine through the pyloric sphincter. In the small intestine, the chyme is further broken down and nutrients are absorbed into the bloodstream. The remaining waste material continues its journey through the large intestine, where water absorption takes place, and finally, it is eliminated as feces. So, in summary, after the esophagus, the food enters the stomach, undergoes digestion, moves to the small intestine for absorption, and then passes through the large intestine before being eliminated from the body.
