Answer :

The organs included in digestion are mouth, pharynx, esophagus, stomach, small intestine and large intestine. The mouth receives food and begins mechanical digestion by breaking down the food.The food mixed with saliva, known as bolus, passes down through the pharynx to esophagus via peristalsis. The partially digested food enters the stomach from esophagus. Further digestion occurs in the stomach by churning the bolus and mixing it with the gastric juices.Chemical digestion takes place in small intestine. It secretes chemicals which break down the food and take away nutrients to blood stream. The undigested food is passed to the large intestine where maximum water is reclaimed before egestion of solid faeces.
