Digestive process begins when food enters the mouth. After the mouth chews and swallows the food, it goes to the throat and then travels to the esophagus or swallowing tube. Next the esophagus, through a series of
contractions called peristalsis delivers the food to the stomach which acts as the storage tank. The stomach contains hydrochloric acid and digestive enzymes which when mix with the food, the food begins to break down into smaller
molecules. Then the food enters the small intestine where in 90% of the food
nutrients have been extracted here and absorbed by the body. The remaining goes to the large infestine as waste product. Finally, this waste products exceeded from the body as a solid matter called stool.
