What do you know about the appendix? What is an appendix used for?

The position of the appendix varies from person to person and can be located in front of or behind the end of the ileum, behind or below the cecum, or across the pelvic margin into the pelvis. According to the domestic physical survey data, the appendix is mostly in the posterior ileal position and the posterior cecum position, followed by the pelvic position, and then the inferior cecum position and the anterior ileal position. In addition, there may be subhepatic and left lower quadrant views, which are rare, but should be considered in the diagnosis of acute abdomen.

Since the position of the appendix varies greatly and it is sometimes difficult to find it during surgery, tracing down the colonic belt is a reliable way to find the appendix because all three colonic bands are concentrated at the base of the appendix.

The appendix grows on the right. Male and female!

** & Introduction:

In young adults, early diagnosis and treatment and smooth recovery are smooth, and a small number of misdiagnoses and complications are more serious due to variable clinical manifestations.

Pathogenic bacteria of acute appendicitis, such as Escherichia coli, enterococci, and bacteroides, already exist in the appendix cavity. In addition to the decline of systemic resistance, the onset of the disease is mainly related to the following factors.

A Appendiceal obstruction: the appendix is slender, curved, narrow, unidirectional opening and small, slow peristalsis, and when there are fecal masses, parasites (pinworms, roundworms burrow or schistosoma eggs are deposited in the submucosal layer to form eosinophilic granulomas), tumors, etc., the parasites in the distal dead space multiply; b Fecal stone compression: fecal masses staying in the appendix cavity will become fecal stones after water is absorbed, which can cause appendix obstruction, and at the same time make the appendiceal mucosa at the pressure ischemia and necrosis, which is conducive to bacterial invasion.

However, gastrointestinal dysfunction causes reflex spasm of the appendix muscles and blood vessels, resulting in the narrowing of the appendix cavity and blood vascularization of the tube wall, which makes appendicitis more prone to occur.

The appendix plays an important role in the fetus and adolescence. By about 11 weeks of development, endocrine cells have appeared in the appendix of the human embryo. These endocrine cells in the fetal appendix have produced various biological ammonia and peptide hormones, as well as compounds that contribute to biological control (self-homeostasis) mechanisms.

The appendix contains a large number of lymphocytes, which can effectively prevent enteritis from occurring.

The appendix is the body's immune organ, it has B cells and T cells involved in immune function, when B cells reach the lymphoid tissue, they will be converted into antibody-producing cells, which can maintain the normal immune function of the body.

The appendix is an elongated and curved blind canal, located in the lower right side of the abdomen, between the cecum and the ileum, its root is connected to the posteromedial wall of the cecum, the distal end is free and atresia, the range of motion varies greatly from person to person, and the appendix can be extended to any position of the abdominal cavity due to the influence of the mesangium. The appendix, located on the lower right side of the abdomen, between the cecum and ileum, is a long, curved blind canal with distal atresia.

The appendix is on the lower right side of the abdomen.

The appendix, also known as the peristaltic process, is a long, curved, blind tube. It is located in the lower right of the abdomen, between the cecum and ileum. The root is connected to the posteromedial wall of the cecum and is distally free locked. The location of its range of motion varies from person to person.

Affected by the mesentery, the appendix can extend anywhere in the abdominal cavity. The appendix is located in the lower right side of the abdomen between the cecum and ileum. This is a long, thin, curved blind canal with distal atresia.
