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 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.

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.

The tailbone

Many people know that the tailbone in the human body is a vestigial tail, 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.
