human digestive system









































the human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. the process of digestion has three stages. the first stage is the cephalic phase of digestion which begins with gastric secretions in response to the sight and smell of food. this stage includes the mechanical breakdown of food by chewing, and the chemical breakdown by digestive enzymes, that takes place in the mouth.
