The vermiform appendix
, generally called the appendix, is a small hollow growth connected to the cecum. The appendix measures an average 9 cm. It is not indispensable to the organism, even if it can contain reserves of bacteria useful to the immune system. It is common for the appendix to become inflamed, causing appendicitis
, and to need surgical intervention, or an appendectomy
. This removal of the appendix does not have consequences for the health of an individual.
