Interesting Facts about the Human Body

It is mind-blowing trying to figure out how the brain works or how the bones fuse together as you grow up. There is so much we don’t know about our bodies, this despite the advancement in technology. This is attributed to the complexity of the working of our bodies. For instance, scientists know very little how the brain functions.

Even if this is the case, the little the science has been able to gather about the working of our bodies has helped us as humans appreciate our individualities. The fact we can do things involuntary is really astounding. The brain, the central processing unit in our bodies is a computer that far surpasses any supercomputer that has been invented.

Even if we don’t know much about our bodies, we hope as technology gets better day-to-day scientists will have an advantage in gleaning more information on the whole working of the body not limited to some parts.

Even if technology gets better enabling scientists to learn more about the human body, there are some parts of the body that will be difficult for scientists to gather information especially the brain.

Well, the following are some of interesting facts about the human body. This is another reason to appreciate your individuality as a human being.

  1. A human body produces an average of 1.7 liters of saliva a day.

  1. Thank you Alexandre. You did the right thing to point out some errors. In the first case, I will have to say the error or mistake is on my part. I will work on it. Same with liver. In these two instances, the brain and liver, I am referring to average weights of the two organs.

    Hahaha…you made a good point on the second part. I agree that is too little…even for me…maybe if a person is taking a meal per day.

    Thank you once again.

  2. I enjoyed reading this very much but I believe, if I´m not mistaken, that there are two things that are not correct or at least they´re contradicting themselves:

    4. The average height (i believe you meant weight) of an adult’s brain is between 8-10 pounds. (3.63-4.54 kilograms)

    and then you write

    20. The largest organ of the body is not the brain but the liver. It is also the heaviest weighing at 1.6kg.

    I know you´re talking about averages but, still….

    The second thing is this:
    11. If you didn’t eat food in a lifetime, having saved all that hunger you experienced then decide to eat, you would consume an approximated 6,000 pounds of food.

    well, if a person lives…let´s say 65 years, that´s 23742 days, what gives us just about 0.25 pounds of food a day. That seems very little to me….and I´m not a guy that eat´s a lot!! 🙂

    I believe, of course, that it´s a problem with your sources and this is not to be a critic, just a check on the facts.

    Anyway, as I said, I enjoyed this reading. Thank you very much
