Question

What is a vermiform appendix?

Answer 1

Hint: Appendix is the structure found in the alimentary canal of humans and ruminants. It has no functions in the human digestive tract but is more significant in a ruminant gut for the digestion of cellulosic diet. It is positioned in the large intestine of the alimentary canal. Other than digestion it has been found that there are other functions of the appendix which makes it useful.

Complete answer:
This answer is a fact-based answer. So, we have to write all the important features of the appendix.
The appendix is ​​a muscular structure attached to the large intestine in the human body. It is a narrow worm-like tube named after the Latin word "vermiform", which means "worm-like".
It extends from the lower end of the cecum, which is a sac-like structure in the large intestine. The appendix is usually $$7-8mm$$ in diameter, $$2-20cm$$ in length, and an average length of $$9cm$$. It is located on the lower right side of the abdomen.
In people with some rare conditions, it can be found in the lower left quadrant of the abdomen. The appendix is ​​composed of the lining of the mucous membrane.
The appendix is a vestigial organ in the human body and its removal does not impact survival.

Note:
Appendix is found to be more developed in ruminants like rabbits where it harbors microorganisms which are cellulolytic in nature, that is which can digest cellulose. In humans it is being viewed as an organ which helps maintain the gut microflora and is also associated with GALT (gut associated lymphoid tissue). In humans the appendix may sometimes become inflamed due to an infection and the condition is thus known as appendicitis.
