What is appendix in our digestive …

The appendix or vermiform appendix is a muscular structure attached to the large intestine in the human body. The diameter of the appendix usually ranges from 7 to 8 mm and its length ranges between 2 and 20 cm, with an average length of 9 cm. The appendix is usually located at the lower right side of the abdomen. The appendix is made of inner mucosa layer just like the rest of the digestive tract and is also known as the vermix or the cecal appendix.
The function of the vermiform appendix in the human body is not fully established yet. Scientists believe that it is a vestigial remnant, that is, it was once useful to humans in the digestion of food, but as we have evolved, it has lost its function and become redundant. Some research studies show that the appendix is rich in lymphoid cells, which help the body fight infections, and hence it could have a role in the body’s immune functions.
