Digestion - Once we eat food, our bodies must break it down into smaller pieces., Mechanical digestion - Mechanical digestion happens when food is broken up by your teeth during biting and chewing, and by the muscles of your stomach (when food is churned up inside the stomach), Chemical Digestion - Chemical digestion involves enzymes breaking down food into smaller pieces. The smaller pieces are absorbed into the blood and carried to all the cells of the body.,
