What is the digestive system ?

The digestive system is a technological marvel of the human body. It helps us to chew digest, extract nutriments and get rid of that which we don’t need. In order to understand the digestive system it is important to know it various organs. The digestive system includes the digestive tract, a tube extending from the mouth to the anus, as well as a host of other organs.

The salivary glands and tonsils complete the mouth area. is surrounded by the lips, cheeks, teeth, and palate, and it contains the tongue. The salivary glands and tonsils are accessory organs of the oral cavity.

The mouth opens into the pharynx which continues into the esophagus. The esophagus in its turn continues into the stomach. Within the stomach the walls of the stomach have an abundance of tube like glands. These are the glands that release all the stomach acid which in turn begins to digest all the food it has received. The stomach leads to the small intestine. The small intestine itself is comprised of many different structures including the duodenum, the liver, the gallbladder and the pancreas. by digestive system blog

The next segment of the small intestine is the jejunum. The jejunum has small glands along it which help it in its major task of absorption. Father the jejunum we reach the ileum, the last segment of the small intestine. After the ileum comes the larger intestine. The purposes of the larger intestine are to convert undigested food into feces. The segments of the large intestine include the cecum, the ascending, transverse, descending and sigmoid colons and finally the rectum
