Final answer:
A ruptured appendix is life-threatening because it can lead to a massive infection of the abdominopelvic cavity, known as peritonitis. Timely surgical removal of the appendix is the usual treatment, and advances in medicine have improved outcomes for such infections.
Step-by-step explanation:
A ruptured appendix is life-threatening because b. it is likely to cause massive infection of the abdominopelvic cavity, a condition known as peritonitis. When the appendix ruptures, it can spill bacteria into the peritoneal cavity, leading to a serious bacterial infection that can spread quickly and has the potential to be fatal. The appendix is a vestigial organ, but appendicitis, or the inflammation of the appendix, can lead to severe complications if not promptly treated.
The role of the appendix in the human body is not completely understood, and while it might have some immune or gut flora-related functions, its removal (appendectomy) is not known to cause any adverse health effects. Appendicitis is usually resolved by surgical removal of the appendix, and advances in surgical techniques and antibiotics have greatly improved survival rates from complications like peritonitis, although these conditions still present significant health risks.
