Picture of Appendix
The appendix is a tube-like piece of tissue that is 4 to 6 inches long and closed on one end. It is attached to the first part of the colon (cecum). The official name of the appendix, the vermiform appendix, means worm-like projection. The wall of the appendix contains lymphatic tissue, which functions in the immune system to make antibodies.
