Appendix (anatomy)

PRACTICALLY NO USE-

A narrow, elongated tube closed at one end, extending from the cecum, a blind pocket off the first part of the large intestine. It is found in only a few mammals. In humans the appendix is about 3 in. (7.5 cm) long, but it varies greatly in both size and its specific location in the lower right quarter of the abdomen. The exact function of the human appendix is unknown, and it is considered to be a remnant of a portion of the digestive tract which was once more functional and is now in the process of evolutionary regression. The appendixes presumably function in digestion in forms with larger ones.

The appendix has no known function in humans. Evidence suggests that our evolutionary ancestors used their appendixes to digest tough food like tree bark, but we don't use ours in digestion now. Some scientists believe that the appendix will disappear from the human body.

The appendix is rich in infection-fighting lymphoid cells, suggesting that it might play a role in the immune system. Whether the appendix has a function or not, it can be removed without any ill effects.

yet evolution does not require that something be functional at each and every "degree of evolution" in spite of meaning, so spectacular straw guy. Evolution purely demands that something on no account be adverse. on the different hand because of the character of diploid chromosomes and recombination it could normally take a protracted time to purge risky mutations from a gene pool. risky mutations are not constantly expressed and so do no longer constantly result somebody's reproductive well-being, notwithstanding they are nonetheless present normally as recessive genes interior the guy's genome and so could properly be inherited with tips from the guy's offspring, returned normally recessively, yet each and every so often dominantly. The human appendix is greater info in prefer of evolution, even with the indisputable fact that, because of the fact evolution is sluggish whilst an organ is rendered vestigial because of the fact it isn't any longer mandatory for survival the genes for the organ can no longer purely disappear or that ought to falsify evolution, the disappearance or sluggish mutation out of existence or into yet another type, of the organ ought to be a sluggish technique. If it happened unexpectedly evolution may well be falsified.

The appendix is a finger–sized tube attached to the large intestine. It has no known function, but it does contain immune cells, which play a role in defending the body from infection.

As far as we know the appendix has no use in human beings. In other animals like birds, it is part of the immune system. There is no evidence to indicate that it serves a similar function is people. Nor do people that have it removed have increase immune system related health problems.

Well, I looked it up on the Encylopedia for you, and I couldn't find any useful purpose for our appendix. Sorry.

No Use. But it bothers when this small sac fills with stool. That causes its inflammation called appendicitis, and has to be removed.

As far as we know it is basically just taking up space and that is why it is no big deal to lose it if you get appendicitis.

It can be used to seal small gaps in window frames.
