The human body is a very complex and intricate system, which doctors still cannot figure out even with the help of modern technologies. The fact is that in the process of evolution, many organs have become rudimentary: it seems that we no longer need them, but in fact, they partially continue to perform their functions. Do you want to know why exactly the appendix is needed and why its removal is scary, do we have a third eye and why the tailbone remains important even without a tail?
Epiphysis
The very third eye, about which lovers of psychics and sorcerers talk so much. In fact, we need this organ to produce melatonin, which regulates circadian rhythms. But in some reptiles and fish, in place of the pineal gland, in fact, there is a so-called parietal eye, which perceives the intensity of light.
Coccyx
The tailbone is not at all a rudimentary organ that we do not need. Indeed, once upon a time there was a tail in its place, and now many muscles and ligaments are attached to it, which directly affect the work of the organs of the genitourinary system.

Appendix
For a long time it was believed that the appendix was a reduced and therefore useless organ. In the United States, there was even a fashion for removing the appendix in newborns, until it turned out that such children are more likely to get sick and are far behind in mental and physical development. It is in the appendix that many beneficial bacteria live, and therefore people, after removing this organ, should be wary of any poisoning. Immunity after surgery is also seriously reduced.
Glands
In our nasopharynx, there are accumulations of lymphoid tissue - tonsils. This is a kind of barrier against bacteria and viruses that a person can catch when breathing. Long-term inflammation transforms the tonsils from a protector into a source of infections, and then they have to be removed.
Spleen
Modern medicine still cannot figure out the exact functions of the spleen. It is only known that it is this organ that produces lymphocytes and antibodies, destroys old erythrocytes and is a kind of depot for blood released during physical exertion.
Paranasal sinuses
Doctors believe that the sinuses can act as a resonator, influencing the formation of our voice. In addition, they also represent a kind of anti-shock buffer during impacts.
Thymus
This is one of the strangest and most mysterious human organs. T-lymphocytes, which fight viruses, are produced in the thymus gland, but its function is not constant and gradually fades away by the age of 30 - therefore the thymus is called the gland of youth.
Vomeronasal organ
Have you seen how cats stare into space with open mouths? They are not at all surprised by what they see - the vomeronasal organ is in the sky in animals, and it enables them to capture pheromones. In humans, the same organ is practically undeveloped.
