This structure helps in the proper movement and removal of waste matter in the digestive system, contains lymphatic vessels that regulate pathogens, and lastly, might even produce early defences that prevent deadly diseases.

Perceived as an atavistic organ lacking physiological relevance, the vermiform appendix appears to be involved in immune function, serving in the maturation of B lymphocytes and the production of immunoglobulin A, in endocrine function, excreting amines and hormones in the 2-3 mL of mucus secreted daily, and in digestive function, by storing beneficial bacteria from where they can recolonize the colon.

Although it is considered an atavistic organ and of no importance to the body, the vermiform appendix appears to have immunoprotective and lymphatic functions, especially in childhood; it is involved in the maturation of B lymphocytes and the production of immunoglobulin A, a storage function for useful bacteria present in the colon, and an endocrine function, producing amines and hormones, which are released in the 2–3 mL of mucus it secretes each day [ 11, 12 ].
