The cecum is also the appendix of the human body, and it is a degenerate organ of human beings. The appendix of adults is mainly related to immune function. Shortly after birth, lymphoid tissue began to accumulate in the appendix, reaching a peak around the age of 20, then rapidly declining and disappearing after the age of 60. However, in the stage of physical development, the appendix can play the role of a lymphoid organ. Promote the maturation of B lymphocytes (a kind of white blood cells) and the production of immunoglobulin A antibodies. Researchers have also proved that molecules involved in the manufacture of the appendix help lymphocytes to transfer to other parts of the body ... From this perspective, the role of the appendix seems to be to expose white blood cells to a large number of antigens in the gastrointestinal tract, that is, foreign substances. Therefore, the appendix can help to inhibit the potentially destructive humoral antibody response. At the same time, it can provide local immune function The appendix absorbs antigens in the intestine and reacts to them. This local immune system plays an important role in physiological immune response and control of food, drugs, bacteria or virus antigens. Therefore, the appendix only has this antibacterial effect on the intestine and has little effect on the growth and development of children.
