The digestive system is a system of digestive organs and has the task of entering food into the human body, to process the food obtained by the action of its juices in order to make it usable for the body, and to expel undigested parts out of the body. In this way, the mentioned system deals with settling the organism as a whole.
The digestive system consists of a large number of organs that are interconnected. It can be represented as one long unbroken pipe whose individual parts continue into each other.
It begins with the food inlet (oral cavity) in which the tongue and teeth are located, followed by the pharynx and esophagus. The esophagus continues into the stomach, the stomach into the small intestine, while the latter continues into the large intestine which again terminates in an opening. To this system are added the liver with the gallbladder, and the pancreas, which secretes its juices into the digestive tract.
