10 Useless Human Body Parts

A list of human body parts that experts believe are useless. Are they really useless? Or perhaps the experts haven’t yet truly discovered their true functions.

A few years back, I was bothered by a stomach pain that required medical attention. I was diagnosed as having an acute appendicitis that needed an urgent operation. Since school classes had just started, my father asked the doctor if they could postpone the operation. But the doctors are too apprehensive, and said, “the healing process will only requires just a week, besides appendix is a useless organ”. Shocked and surprised to hear those statements, I begun questioning my self, “are there really are useless body parts?”
Now, I’ve done some researched and found out that experts believed there are at least 10 body parts that are useless. Before you continue reading the rest of the article, I will leave you a puzzling question: do you agree with the experts findings or you have a dissenting opinion. It is your call. Here is the list:

  1. Plica Semilunaris

    Yes, you have a third eyelid and it is called the plica semilunaris. It is a small fold of bulbar conjunctiva located on the inner corner of the eye. An accessory organ of the eye, plica semilunaris is a left over from what’s known as a “nictitating membrane.” For most mammals, it is a vestigal organ, which is still present in chickens, lizards and sharks. But for humans, plica semilunaris serves an important purpose: it produces a fatty substance (rheum) that collects foreign bodies such as dirt and dust from entering the eye and damaging the cornea. This foreign bodies is then deposited hear the tear duct, ready to be brushed away in the morning.

  2. Body Hair

    Three million years ago, human were once hairier. Earth temperature at that time was much colder than today so our body hair is a good insulation for the colder climate. But by the time Homo erectus arrived, the ability to sweat meant we could shed our woolly ways. Today, having much body hair is annoying that people having this predicament seek the help of dermatologists. Thanks to the now popular hair waxing, excess body hair are remove with ease. So the question arises, “Do we really need body hair?”

  3. Sinuses

    Humans have four pairs of sinuses that are found in the bones of the head and face. These air-filled spaces are lined with a moist, thin layer of tissue called a mucous membrane. The mucous membrane secretes mucus that traps dust and germs that are in the air we breathe. Doctors don’t really know much about sinuses but some researchers think they keep the head from being too heavy. Sinuses also give you the pitch and tone of our voice.

    it’s an eye opening. i will do my own research too and check if some of the body parts really don’t have use at all

    All of those things you posted, you also posted a use for each one. None of them are useless except the very last one.

    That is really interesting. It looks as if they all have uses at particular times and then become redundant. Good work.

    I love this article!

    I was just reading this thing that says male nipples aren’t exactly useless- if stimulated to do so, men can lactate. It’s hard but, it has happened. There was even a tribe somewhere where it’s common…
    Tonsils and adenoids serve a purpose too–they help doctors make money.

  26. Bill M. Tracer Says...

    Joshua and Boomboom are right, male nipples may not serve a lactating function like those of females, but they are most definitely an erogenous zone. And that is a function.

    Great article, very well written piece!
    I can agree with some on your list,
    since they can be easily removed
    (tonsils, appendix, wisdom teeth)
    the others I’ll have to learn more about!


  31. Jo Oliver Says...

    Very original piece. Well done. I am a nurse. So, of course, I loved it! But the body hair….could have lived without seeing that.

    what a cool article x
    I believe that the function of the appendix has now been discovered.

    Doctors believe that in the event of a severe stomach bug – the body evacuates the good bacteria from the digestive system along with the bad……the appendix (by design)is a hideaway for good bacteria – it remains unaffected and allows good bacteria to spread once the stomach bug is gone.

    As you suggest, I believe that all these physiological oddities have or had a purpose – we just havn’t figured them out yet.

    Very interesting stuff though x

    Very interesting article…as far as I know the sinus are v important though, as the mucous and tiny hairs that line the nasal passages stop us from breathing in airbourne germs. And presumably they might have something to do with balance as they are connected to the ears as well…

    i’ve never thought of these body parts before. now you left us all thinking. hehe. thanks po for all these infos.:)


  41. Kedyn Says...

    On May 8, 2009 at 3:57 pm

    Interesting but highly opinionated. I’m a second year med student and know important purposes for all these structures. Removing tonsils used to be a routine operation for children that has now stopped because tonsils are an important part of the immune system. Similarly the appendix contains much hemopoietic tissue that produces blood

    male nipples. maybe they dont serve a useful purpose but you guys just would look strange without them! haha. good article papaleng!

    If you know anything about evolution you know that you are about as intelligent as a baby sticking his head in a blender.

    It’s called College…. maybe you should check it out.

    You claim these have no uses, but then list their functions in your descriptions? You are wrong about most of these, go and do some research.

    Also, appendicitis can be fatal if left untreated so no the Doctors weren’t too ‘apprehensive’.

    This a great article but I should agree with Kedyn somehow.
    Some of these body parts do have important uses. :)

    “Sinuses keep the head from being too heavy.” Just saying that will already give you an idea that it is really useful, just imagine your head as compact and heavy as a stone(of the same size as the head). Just like pipe instruments, the sinuses will also give us the ability to have resonance and pitch when speaking. It prevents us from speaking monotonously.

    Tonsils take part of the immune system.

    And just imagine, watching horror movies without even feeling anything. The arrector pili is the one that gives you goosebumps. hehe

    There are still many uses of them but I just don’t want to utter many medical jargons. :)

    nice article, papaleng…I am in total agreement with you!


  50. Mark Says...

    Contrary to popular belief, the fact is NONE of these body parts is “vestigial”. The coccyx for example, is not “the left over of a vestigial tail” the coccyx is necessary for humans to evacuate their bowels (you know,pooping). “Evolution” never happened, it’s a scam that’s been popularized and to see people promoting the “vestigial organ” nonsense is ridiculous.

    Just because scientists may not know the purpose of something, does not make it “vestigial” or “useless” it just means human knowledge is lacking.
