Its made up of five things: Salivary glands, pharynx, esophagus, tongue, and teeth. The mouth makes it easier to digest and easier to swallow. The mouth Salivary glands It kills bacteria when its braking down the food. It also plays a very important role in breaking down starch into glucose. Pharynx
anus Just a passage really and also where the food is sent into the correct way. Esophagus The tube that carries the food from the pharynx to the stomach. Tongue The tongue is not just used for tasting. It also helps in chewing and swallowing. This process is basically, the physical simplification of food. Teeth chewing makes digestion easier for other organs to break down the food and its nutrients. larynx carries air towards the lungs through the trachea, and the oesophagus. The larynx is considered to be the the first organ of the respiratory system that is not shared with the digestive system. larynx The epiglottis seals the windpipe while swallowing, so food won't go to the lungs so you wont choke. epiglottis small Intestine The small intestine is divided into three parts. The duodenum is the receiver of simplified food. The duodenum is the shortest part of the intestines, a lot of chemical digestion takes place in it. The jejunum moves the rest of the food to the ileum. The ileum absorbs the nutrients that have been missed by the jejunum. large Intestine The colon is responsible for the absorption of water and salts from the digested foods. The cecum is attached to the appendix and is also the connecting pouch between the small and the large intestines. Stores some fecease and help with defecation.
