anatomy of the appendix. Does it have a function in humans?
The vermiform appendix (from Latin, vermiform or wormlike, and appendere, to hang upon) is usually 6 to 9 cm in length, arising from the convergence of the three taenia coli at the base of the cecum. It is now considered an immunologic organ that participates actively in the secretion of immunoglobulins (Ig), particularly IgA. Some theorize that the appendix may also act as a “safe house” for normal intestinal flora following periods of acute infection.
