Digestive system of Human body.

Digestive system starts from mouth to anus. different parts of the system are Oral Cavity, Esophagus, Stomatch, Large instestine, Small intestine, Rectum etc. When we enter some food in our mouth, our teeth help to cut and grind that food. This food is thrown in pharynx and then travel through Esophagus and reaches to Esophageal Sphincter and finally this food reaches in Stomach. Crossing Duodenum this food reaches in intestine. The colon absorbs H2o, produces vitamins, produces mucous and forms & exples feces. liver and pancreas also helps in digestive system. Finally the wastage goes outside thorugh rectum.
