Smooth muscles in the digestive tract slowly move from the esophagus to the stomach where it is mixed with stomach acid and enzymes and then released into the small intestine where small particles are absorbed. The remaining food, which is indigestible, is held in the colon in water is reabsorbed. Eventually, that is expelled from the body as feces.

The lower esophageal sphincter keeps food from coming back up, or vomiting. When you have to vomit, the sphincter opens allowing the food to come back up. There is another sphincter, the pyloric sphincter which leads into the small intestine. Hope this helps!
