How long is the human intestine?

Human intestines are generally about 6.5-8.5 meters.

Human intestines include duodenum, small intestine, large intestine, etc. The duodenum is the shortest in length, about 12 fingers in parallel, about 20-25 cm, while the small intestine is relatively long, about 5-7 meters, enough length to help the full absorption of food. When inflammation, ulcer or tumor occurs in the intestine, it can be diagnosed by enteroscopy, abdominal CT examination, etc. The large intestine of human is mainly stored in feces. When the function of the large intestine is enhanced, it may strengthen the absorption of water in the intestinal tract and easily cause constipation symptoms.
