Totally Useless Organs

#1 Appendix

The appendix is a narrow, muscular tube that attaches to the large intestine. Its purpose is to digest cellulose. The appendix was a more important and necessary organ when the body was introduced to more vegetables. When the human diet consisted of mostly plants, the appendix was extremely important.

#2 Appendix Removal

In today's world, the appendix isn't a necessary organ. In fact, sometimes the appendix can become infected and burst. About 300,000 Americans have their appendix removed. Doctor's are even removing the appendix in children when no pain or other sings of an attack are present as a precautionary measure.

#3 Gall Bladder

This is just another part of the body that is sometimes surgically removed. The gall bladder is a small organ that is known to store bile as well as aid in digestion. However, the gall bladder can sometimes produce gall stones and cause people to not be able eat without vomiting. If this is the case, out it goes. Many people get a blockage from the stones and it can cause death as the bile backs up.

#4 Male Nipples

This doesn't need much of an explanation. Males don't breastfeed, so nipples really aren't needed. I guess they serve as decoration. Nipples are a vestige of our early, gender-bending days in the womb. ... Whatever your sex, everyone starts off as a woman in the womb. For the first several weeks a developing embryo follows a "female blueprint," from reproductive organs to nipples. Once born, they are not a needed part of the male body.

#5 Wisdom Teeth

Wisdom teeth are those that are located in the back of the mouth. These teeth were once very helpful, especially when humans had a diet that consisted of a lot of tough meat. Wisdom teeth, at this time, allowed humans to properly chew their food.

#6 Evolution Has Already Ceased Growth Of Wisdom Teeth In Many Humans

Nowadays, many people don't even get them. And if they do, they're surely in for a surprise. Generally wisdom teeth are removed, due to them growing in wrong or causing pain. These chompers can cause a lot of pain either way! It may be evolution, but 1 in ever 6 people never develop wisdom teeth at all.

#7 Arrector Pili

The arrector pili are extremely small muscle fibers that are attached to each hair follicle on your body. It is known to make the hairs stand, which causes goose bumps. Most mammals, including humans have these small muscle fibers; however, they serve no real purpose. They are much more helpful when it comes to animals with much more hair because they provide a layer of insulation. They normally appear when there is a change in body temperature, not when frightened, though the body does get warmer when suddenly afraid. So, they are on the list of part not required.

#8 Coccyx

The coccyx, more commonly known as the tailbone, is the last part of the human vertebrae. It consists of five separate or fused vertebrae and is the remnant of the vestigial tail.

#9 The Coccyx Is Not Totally Useless

It does allow many different ligaments, tendons, and muscles to attach. It is also helpful when it comes to weight-bearing. In any case, the coccyx is generally much more important in those mammals with tails than it is of modern humans.

#10 Tonsils

The tonsils are another useless part of the body that can cause certain people a lot of pain. Open your mouth wide and you'll see a tonsil on each side of your throat, unless you have had them removed. Tonsils are lymphoid tissues that are prone to becoming infected and swelling up. And you know what that means, surgery to get rid of âÂ€Â˜em!

#11 Adenoids

Adenoids are masses of lymphoid tissue that are located at the very back of the nose. These tissues are part of the immune system and trap bacteria that can cause viruses. However, they only provide a strong defense against bacteria that is inhaled.

#12 The Adenoids Shrink With Age

As you grow, your adenoids shrink, which makes them useless. They are only helpful when you are a child.

#13 Sinuses

Sinuses are one part of the body that doctors really don't know too much about. We have a lot of them, but they're nothing but air-filled spaces.

#14 Doctors Are Not Even Sure What The Sinus Cavity Is For

Some say that they insulate our eyes while some doctors say that they influence our voice's tone and pitch. In any case, no one exactly knows what they're for, but we do know that they cause headaches. Sinuses are also famous for infections.

#15 Body Hair

Without a doubt, once humans used to have much more hair. About 3 million years ago, our ancestors were completely covered by it. But with the emergence of Homo Erectus, body hair lost its use.

#16 Body Hair Is For Our Ancestors

The fine hairs that cover our bodies, which have replaced the thicker ones seen on our close relatives, are thought to be an evolutionary leftover from our hairy ancestors. Science believes the hair remaining is to help detect parasites or to help secrete pheromones. Yet, this is all speculation. Since many humans have little to no body hair, and others are covered with it, it is believed this is due to hormone levels which can be controlled, and rid hair from the body for future humans.

#17 Plica Semilunaris

Better known as your third eyelid, or maybe not, this organ in our bodies is just one of the many parts that we don't need. If you pull up on each of your eyelids, the plica semilunaris will be exposed. This part of the eye is known to produce "sleep," or that weird crust you have in your eyes when you wake up. Thank you plica semilunaris. How could we live without waking up with weird stuff in our eyes?
