Where is the appendix located

The human gastrointestinal tract is very rich in organs and tissues, and each organ has its function. If one of them has a problem, it will be quite troublesome, and some nutrients consumed by the patient will not be absorbed and digested quickly. Therefore, relevant treatment must be carried out in time. The appendix is ​​still very critical for the patient himself. The main function of the appendix is ​​to play a role in digestion, but many people will suffer from appendicitis, and the incidence of this disease is still very high. In this case, it is best to detect and treat it early, so that the condition will not be as serious as imagined, and it will not cause so many sequelae during the onset, so that the nutrients taken into the body can be fully absorbed and digested.

Location:

The cecum is the thickest, shortest and most passaged section of the large intestine. It is the starting part of the large intestine. The lower end is a dilated blind end. The left side is connected to the end of the ileum. The upper part continues with the ascending colon, and the ileocecal valve is the boundary between the ascending colon and ileum.

The ileocecal valve is composed of two semilunar valves, upper and lower, formed by the protrusion of the terminal ileum into the cecum. The function of this valve is to prevent the contents of the small intestine from flowing into the large intestine too quickly so that food can be fully digested and absorbed in the small intestine, and to prevent the contents of the cecum from flowing back into the ileum. The cecum is located in the right iliac fossa. The high cecum can be above the iliac fossa and even reach the bottom of the right lobe of the liver. The low cecum can reach the small pelvis.

1. Surrounding relationships

It is surrounded by indirect cavities (sometimes mesentery appears on the posterior and medial sides), with the anterior lateral abdominal wall in front; the posterior abdominal wall and iliopsoas muscle in the back; the ileum and mesenteric sinus inside; the lateral colic groove outside; the ascending colon above; and the pelvic cavity below.

2. Internal relations

There are three channels, namely, the ileum inward, the ascending colon upward, and the appendix inward and downward. The three colon bands on its surface (omental band, mesangial band and independent band) are concentrated at the root of the appendix.
