Intestine

The intestine is the largest part of the digestive tract. It is a four to seven meters long, tube-shaped organ, its surface is up to 300m ² large by the multiple convolution. The intestine is divided into the small intestine and the colon and has the task of catching the ingested food to absorb water and excrete waste products of digestion.

The gut has the task of absorbing nutrients and plays a major role in the immune system. In the intestinal mucosa there are immune cells that create antibodies and release them into the gut to protect it from harmful substances. In addition, the intestinal mucosa is colonized by a variety of bacteria that keep the immune system on the go and protect the gut against disease-causing germs. If the immune system of the intestine weakens, it affects the entire body. It is therefore important that celiacs choose gluten-free food. Incompatible substances can damage the intestinal cells and weaken the immune system.
