The intestines of a human being are about a meter in meters.
The length of each person's intestine is different, and there is a big difference, about meters, including the small intestine and the colon. The small intestine is divided into three parts: duodenum, jejunum, and ileum, with a total length of about 3 meters and 5 meters, and the colon is divided into six parts: cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum, with a total length of about meters.
The function of the intestines.
1. The intestine is the largest digestive organ.
99% of the body's nutrients are digested and absorbed by the intestines, which are the main digestive organs of the human body, and about 99% of the nutrients required by the human body are absorbed and digested by the intestines. On average, a person digests about 50 tons of food in their lifetime.
2. The intestine is the largest immune organ.
The intestinal lymphoid tissue is the most developed, gathering 70-80% of the body's immune cells (such as macrophages, T cells, NK cells, B cells), and the immunoglobulin Iga produced by the intestinal immune system accounts for 70% of the immunoglobulins produced by the human body.
3. The intestine is the "second brain" of the human body
The enteric nervous system can sense the information of various substances in the intestine ingested by humans, and autonomously control the behavior of the intestine independently of the brain. Feeling unhappy may be accompanied by a lack of appetite or indigestion, because the intestines can feel the brain's reaction through information transmission, and bad emotions such as nervousness, anxiety, depression, and anger can lead to disorders in the physiological functions of the gastrointestinal tract and cause an imbalance in the intestinal microecological environment.
4. The flora in the intestines.
The normal flora in the intestine has a variety of physiological functions, can synthesize a variety of vitamins, use protein residues to synthesize essential amino acids, participate in the metabolism of sugars and proteins, promote the absorption of minerals such as iron, magnesium and zinc, affect weight and digestion, resist the risk of infection and autoimmune diseases, and can also affect the body's response to drugs.
