The stomach vigorously churns food, mixing it with gastric juices. This process, known as mechanical digestion, involves the rhythmic contractions of the stomach muscles, which help break down food into a semi-liquid form called chyme. The gastric juices, which contain hydrochloric acid and digestive enzymes, further aid in the breakdown of proteins and kill harmful bacteria. Together, these actions facilitate the digestion and absorption of nutrients in the intestines.
