Anatomy of the digestive- tract, The digestive tract is made up of organs that food and liquids travel through when they are swallowed, digested, absorbed, and leave the body as feces. These organs include the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus
Gastrointestinal-Tract Anatomy
The gastrointestinal- tract in humans begins at the mouth, continuing through the esophagus, stomach, and small and large intestines. The GI tract is about 9 meters in length.
There are many supporting organs, such as the liver, which helps by secreting enzymes that are necessary for the digestion of food.
The human GI tract can be divided into two halves, namely:
- Upper GI tract
- Lower GI tract
It includes the teeth, tongue, and buccal mucous membranes containing the ends of the salivary glands that continue with the soft palate, floor of the mouth, and underside of the tongue. Mouth functions by chewing the food, constantly by the muscular action of the tongue, cheeks, and teeth through the lower jaw and upper jaw.
Pharynx
The pharynx is enclosed in the neck and functions as part of both the digestive system and the respiratory system. It protects the food from entering the trachea and lungs.
Stomach
This is where most of the digestion takes place. The stomach is a J-shaped bag-like organ that stores the food temporarily, breaks it down, mixes and churns it digestive fluids and finally, passes it along to the small intestine
Esophagus
A muscular tube-like structure that functions by carrying food to the stomach. Once the chewed food reaches the esophagus from the mouth, the action of swallowing becomes involuntary and is controlled by the esophagus.
