Intestinal Gate Posterior

Intestinal Gate Posterior: how it works

The intestinal hilum posterior is the opening that connects the embryo's hindgut to the rest of the intestine. It is an important element in the digestive process, allowing food to pass through the intestines and be absorbed by the body.

The fetal hindgut, or rectum, is the last part of the intestinal tube and is located in the abdominal cavity. It extends from the end of the colon to the anus and performs an important function - it holds feces and removes it from the body.

The hilum posterior is a kind of “gate” that controls the passage of food from the rectum to the rest of the intestine. This occurs thanks to the sphincters - ring muscles that surround the intestinal gate and control their opening and closing.

When food passes through the posterior intestinal gate, it moves through the colon and further along the digestive system. The body absorbs useful substances from food, and indigestible feces are removed from the body through the anus.

Although the hilum posterior is little known to the general public, it plays an important role in the digestive process. The health of the intestinal system is key to maintaining overall health, so it is worth paying attention to proper nutrition and regular medical examinations.

Rear Intestinal Gate (rectal isthmus) - the opening through which the hindgut is connected to the rest of the intestine of the embryo. They appear in the frog at three to four weeks of embryonic development. In general, the intestinal openings of fish, amphibians, and some reptiles are located at slightly different locations in their digestive systems, but in snakes and lizards they are located along the peritoneum. The hindgut hilum forms at the four to eight cell stage around the opening of the hindgut, which appears as a small slit in the lower abdomen. The function of the intestinal gate is to allow the intestines to develop correctly and communicate with the rest of the body.
