The Most Useless Parts of the Body


As humans, we have evolved errr… changed over time. Because of the complexity of our bodies, certain organs and parts seem to become less and less needed over time. Whether you’re some big fan of evolution or you’re completely against it, there are parts of the human body that are no longer needed to live or survive. While they may have been necessary to live in the past, in today’s world, there are many different body parts that we just don’t need! Here is a list of the top 10 body parts that are completely useless.

10. Plica semilunaris

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?

9. 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 his 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.

8. 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. 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!

7. 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. However, the coccyx isn’t completely 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.

6. 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 ‘em!

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

4. 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. 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.

3. 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.

2. 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.

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. However, 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

  1. Funny thing is is that male nipples can produce milk if stimulated for weeks (enough milk to keep an infant alive). Women and men do not need to be pregnant to produce milk, the nipples just need stimulation. There are african tribes where the men also help breastfeed the children. I guess it’s a way of making sure your ofspring survives if the mother dies but it is rare today.

  2. Well, I really liked your article but I have to say that I don’t quiet agree that tonsils are not necessery. I don’t have tonsils because I had them removed at the age of 8 but since then whenever I get sick I always have a very high and almost impossible to bring down fever which my doctor says it is because I don’t have tonsils.

  3. Sinuses are important!!!

    Sinuses chief function is to produce a special mucus that keeps the inside of the nose moist and protects it from dust, dirt, pollutants, and microbiologic organisms. The mucus layer is propelled by tiny hair cells called cilia toward the back of the nose and throat, where it is swallowed.

    As an example: Frequent NetiPot use can actually trigger sinus infections because your clearing the mucus that protects you. However moderate NetiPot use is OK. Trust me – I’ve learned that the hard way.

    Whats up, yo the only thing useless in this tonsils, it controls nothing really, cept how deep your voice may be, and it reminds us we aren’t flawless lol…we feel it often.

    Praise Cthululululululu.

    • I think that you may be confused with the Larynx versus the tonsils. Tonsils do not determine how deep your voice gets, these immunocompetent tissues are the immune system’s first line of defense against ingested or inhaled foreign pathogens.

  5. Every organ is important it performs a specialized function and it is therefore very dangerous for you to assume that an organ in useless! #5 about adenoids, for heaven’s sake! bacteria does not cause viruses! they are however two very completely different etiologic agents, please refrain from putting your OWN PERSONAL opinion on matters you do not know. for one, you are NOT a Doctor to make these silly assumptions, the internet is full of trash. please do not add more.. – Dr.AMCM

  6. I seriously laughed out loud when I read “bacteria that can cause viruses”
    this article is a joke written by some high school schmuck based solely on his opinion and imagination.
    If it wasen’t then I feel bad for the uneducated schmuck. No hard feelings just my opinion.

    So when we become an adolescent why not just have #8, #6, #5, #2 and # 1 removed from our bodies. #8, #6 and #5 are gone from my body so know I’m working on #2 and #1 and lets face it, #1 The Appendix can literally kill you when it bursts and no medical treatment is available !!

    • um Peter you said ” The Appendix can literally kill you when it bursts and no medical treatment is available !! ”

      Your information is completely wrong !

      My appendix burst, and I was operated on and did nearly die… but treatment IS available for those whose appendix actually burst.
