9 Organs of the Human Body Which No One Knows the Purpose of

Even now in the 21st century, there are certain organs in the human body whose functions scientists still don’t fully comprehend. We at Bright Side decided to tell you about a few of those parts of the body that most of us have heard about but could never understand what their purposes were.

 

1. The epiphysis

1. The epiphysis

This gland produces the hormone melatonin. It’s produced only when it’s dark and is regulated by the body’s circadian rhythms. Some fish, amphibians, and reptiles have a parietal (or third) eye instead of an epiphysis. It perceives different levels of light intensity but cannot produce images. It has a retina and the equivalent of a lens, but its functions are comparable to those of the epiphysis in humans: the regulation of circadian rhythms. It’s entirely possible that when esoterics talk about the third eye, they have the epiphysis in mind. But for us, the epiphysis no longer has any function comparable to the eyes.

 

2. The tailbone

Many people know that the tailbone in the human body is a vestigial tale, but few know about its significant number of important functions. It helps to fix in place many different muscles and ligaments that are required for the functioning of the intestines and the genitourinary system. In addition, the tailbone plays a role in distributing physical loads correctly when you change the position of your body.

 

3. The appendix

There are certain kinds ofbacteria that live within herbivorous animals which help the latter digest cellulose. In humans, however, such bacteria are much less significant. The appendix, of course, is always at risk of becoming inflamed, in which case it requires urgent removal. It’s because of this that removing the appendix at birth was for a long time a standard policy in the USA. However, it turned out that children were then susceptible to slower physical and mental development and became sick more often. The appendix is a kind of unique “farm” of useful bacteria which live inside our intestines. People who have had their appendix removed often find it more difficult to recover from being poisoned, and their immunity is often weaker.
