Digestive System (Part 2)

It takes about seven seconds for food to move from the mouth to the stomach. Pupils follow food from the mouth through digestion, exploring where mechanical and chemical digestion occur. Saliva, enzymes, acids, and chyme are a small portion of the vocabulary taught in the 34th video in a series of 47 which ends by exploring cephalic, gastric, and intestinal phases of digestion.
