What organs does the digestive tract include?

The health issues of the digestive tract need to be paid attention to, because some diseases caused by the digestive tract will cause harm to our health. The digestive tract includes organs such as the mouth, pharynx, esophagus, stomach and small intestine, and we should also pay attention to their functions.

1. What organs does the human digestive system include?

1. The human digestive system consists of two major parts: the digestive tract and the digestive glands.

The human digestive tract includes the mouth, pharynx, esophagus, stomach, small intestine (including duodenum, jejunum, and ileum) and large intestine (including cecum, appendix, colon, and rectum). In clinical practice, the digestive tract is often divided into the upper digestive tract (the part above the duodenum) and the lower digestive tract (the part below the duodenum).

2. Digestive glands include oral glands, liver, pancreas and many small glands on the walls of the digestive tract. Their main function is to secrete digestive juices.

Throughout its life activities, the human body must absorb nutrients from the outside world as a source of energy for its life activities in order to meet the needs of a series of metabolic activities such as human development, growth, reproduction, and tissue repair. The organs of the human digestive system work in coordination to physically and chemically digest food taken from the outside, absorb its nutrients, and excrete food residues from the body. It is an important system to ensure the normal metabolism of the human body.

2. How are the upper and lower digestive tracts distinguished?

1. The distinction between the upper and lower digestive tracts is artificial and is based on their different locations on the ligament of Treitz. The digestive tract above this ligament is called the upper digestive tract, and the digestive tract below the Treitz ligament is called the lower digestive tract.

2 Ligament, also known as the suspensory ligament of the duodenum, is a bundle of muscle fiber cords that runs from the right corner of the diaphragm downward to the duodenal jejunal flexure, fixing the duodenum and jejunum to the posterior abdominal wall. The ligament of Treitz is an important landmark for identifying the starting point of the jejunum.
