Appendicitis
The appendix is part of the large intestine. It is a tubular formation projecting from the cecum (the beginning of the large bowel). It contains lymphatic tissue (part of the immune system) and secretes mucus.
Diverticulitis
Diverticular disease is the condition of having (sac like) projections in the wall of the colon. The increased pressure in the bowel lumen results in mucosa projections through weaknesses of muscle layers in the colon wall. They look like the “blisters” on a car’s tire.
Colon Cancer
Achalasia is of a Greek derivation and means lack of relaxation. It is caused due to damage to the nerve plexus of the esophagus.
