The duodenum, the fasting intestine and ileum make up the small bowel in humans six to seven meters in length. Following this, the large intestine begins. It begins with the cecum and ends at the rectum. The appendix is a short 'dead' piece that ends with a vermiform appendix, also called appendix. Appendicitis is an inflammation of the appendix. Wrong people often speak of appendicitis.
The function of the intestine is digesting and absorbing nutrients. First there is a digestion process already starts in the mouth.
Body Juices from different organs end up in the intestine to the digestion process in motion. The nutrients can then be digested by the intestinal wall and into the blood to absorb.
Separates substances from the liver via the bile into the intestine. These wastes leave the body with the stool.
The intestine has a peristalsis. This is a squeezing propulsion that makes the food comes out in the intestine. If this is too violent peristalsis may result in diarrhea.
Many lives in the gut cavity bacteria (intestinal flora) that help with digestion by breaking down substances into easily absorbed nutrients. It is mainly the production of vitamin K by these bacteria is important. Newborns still lack these bacteria, making them a vitamin K deficiency bleeding disorders can get. Each newborn will therefore get a milligram of vitamin K. Without this flora, man can not survive. Antibiotics fight bacteria and are therefore harmful to the intestinal flora.
In other species, the total length of the intestinal tract depends on the diet. Carnivores or meat-eaters have shorter intestines needed to digest their meat, and herbivores or herbivores need a longer intestine, because the slower digestion of plants (the intestine of a sheep, for example, about 28 meters).
Man is an omnivorous (omnivorous) and has a gut in length between that of a carnivore and a herbivore is.
