When a piece of meat is eaten, it first undergoes mechanical digestion in the mouth, where it is chewed and mixed with saliva. It then travels down the esophagus to the stomach, where gastric juices break it down further into a semi-liquid form called chyme. This chyme moves into the small intestine, where enzymes from the pancreas and bile from the liver aid in the digestion of proteins and fats. The resulting nutrients are then absorbed through the intestinal walls into the bloodstream, where they are transported to cells throughout the body.
