Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Appendix.
- Appendix is a vestigial hollow tube that is closed at one end and is attached at the other end to the cecum, a pouch-like beginning of the large intestine into which the small intestine empties its contents.
-
The appendix, which averages about 9 cm in length, is thought by some scientists to serve as a reservoir for beneficial gut bacteria, helping to restore the digestive system following episodes of severe diarrhea.
-
While one theory suggests it has a supportive role in gut health, others believe it is simply a vestigial organ, left over from human evolution.
-
Interestingly, its removal does not result in any noticeable health issues, indicating that it may not be essential for modern human survival.
