Give some examples for chemical digestion?
Saliva contains an amylase enzyme called ptyalin, which breaks starches down into dextrose and maltose by adding a water molecule into the starch compound. Once food is swallowed, powerful muscles in the esophagus push it downward into the stomach in a continuous wave motion.While your food is still in your mouth, glands in your cheeks and tongue send signals to your brain, which prompt glands in your stomach lining to begin secreting gastric juice. Once the food hits your stomach, more gastric juice is produced. Your stomach mixes the juice in with the food as it churns, dissolving it into a thick, creamy liquid called chyme. Little by little, chyme is deposited into the small intestine.
