Blockage in which organ can cause appendicitis?

• A. Appendix
• B. Liver function
• C. Gallstones
• D. Peritonitis

Answer: (A)

Blockage occurs in the appendix. When the opening of the appendix gets blocked, secretions and bacteria that normally drain away begin to build up. This increases pressure inside the appendix, reduces blood flow, and allows bacteria to multiply, leading to inflammation and the pain of appendicitis. Common causes of the blockage include a hard piece of stool (fecalith) or swollen lymph tissue; in kids, lymphoid hyperplasia is a frequent trigger.

The liver, gallbladder (gallstones), and the lining of the abdominal cavity (peritoneum) are different organs or areas. Blockage in those structures does not initiate appendicitis, which is why this blockage is the key initiating event in the appendix.
