Gut Hind

The hindgut (Metenteron) is an anatomical structure that is a curved tube of intestine located behind the last loop of the small intestine (terminal ileocecal region) and occupying the space between the midgut and the rectum. The hindgut runs along the side wall of the abdominal cavity and has a length from several centimeters to several tens of centimeters, depending on the individual characteristics of the organism.

The hindgut performs important functions in the digestive system. It is responsible for absorbing fluid and electrolytes from the large intestine into the body and protecting the intestines from infection. The hindgut also participates in the body's metabolic processes and synthesizes some vitamins, hormones and other biologically active substances.

The structure of the hindgut can vary from person to person. In most cases, these are two tubes consisting of the intestinal mucosa and the muscular layer. Thin muscle tissue helps with peristalsis, which is the movement of intestinal contents. Also in the hindgut there are vessels, nerves and lymph nodes that are involved in the regulation of digestion and immunity.
