digestive system

The general name of digestive organs, which consists of digestive tubes and digestive glands.

The digestive tract of human body is long and tortuous, including mouth, pharynx, esophagus, stomach, small intestine, large intestine and anus. The small intestine is the longest and the most important place to digest and absorb nutrients, with a total length of 5~7 meters. It is coiled in the middle and lower part of abdominal cavity and divided into duodenum, jejunum and ileum in turn.

The length of the duodenum is about 12 fingers together, about 25~30 cm. Because the lumen receives acidic chyme, pancreatic juice and bile propelled by the stomach, some people call the duodenum the "Yangtze River Delta" of the digestive system. There is no obvious boundary between jejunum and ileum, jejunum accounts for 2/5 and ileum accounts for 3/5. The large intestine is connected with the back of the small intestine, with a total length of 1.5 m, and is divided into three parts: cecum, colon and rectum.

Digestive glands are divided into two categories: one is located outside the digestive tract; Macrodigestive glands visible to the naked eye, such as salivary glands, liver and pancreas, all have ducts leading to the digestive tract, and the secreted digestive juice can flow into the digestive tract through the ducts. The other is the small glands distributed on the digestive tract wall, which can only be seen under the microscope, such as gastric glands and intestinal glands.
