Where does digestion being?

Digestion begins in the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes that start the process of carbohydrate digestion. Once swallowed, the food travels down the esophagus to the stomach, where it undergoes further breakdown by gastric juices. This initial phase is crucial for preparing food for the subsequent stages of digestion and nutrient absorption in the intestines.
