The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts:. The treatment of food in the digestive system involves the following seven processes:. Propulsion is the movement of food along the digestive tract.

The gastrointestinal tract GIT consists of a hollow muscular tube starting from the oral cavity, where food enters the mouth, continuing through the pharynx, oesophagus, stomach and intestines to the rectum and anus, where food is expelled. There are various accessory organs that assist the tract by secreting enzymes to help break down food into its component nutrients. Thus the salivary glands, liver, pancreas and gall bladder have important functions in the digestive system. Food is propelled along the length of the GIT by peristaltic movements of the muscular walls. Information on re-publishing of our images. The primary purpose of the gastrointestinal tract is to break food down into nutrients, which can be absorbed into the body to provide energy. First food must be ingested into the mouth to be mechanically processed and moistened.

As adults, we know that a healthy digestive system is essential for good health because it converts food into raw materials that build and fuel our body cells. The organs of the digestive system can be separated into two main groups: those forming the alimentary canal and the accessory digestive organs. The alimentary canal, also called the gastrointestinal tract, is a continuous, hollow muscular tube that winds through the ventral body cavity and is open at both ends. Its organs include the following:. Food enters the digestive tract through the mouth , or oral cavity, a mucous membrane-lined cavity.

The digestive system includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated. The digestive tract, also called the alimentary canal or gastrointestinal GI tract , consists of a long continuous tube that extends from the mouth to the anus. It includes the mouth, pharynx , esophagus , stomach , small intestine , and large intestine. The tongue and teeth are accessory structures located in the mouth. The salivary glands, liver , gallbladder , and pancreas are major accessory organs that have a role in digestion.
