Whether you're a big fan of evolution or completely against it, there are parts of the human body that are no longer necessary for life or survival. Although they were necessary for survival in the past, there are many different body parts that we don't need in today's world! Here is a list of the 10 best body parts that are completely useless.
10. Plica semilunaris
Better known as your third eyelid or not, this organ in our body is just one of the many parts we don't need. If you pull each of your eyelids up, the plica semilunaris will be exposed. This part of the eye is known to create "sleep" or the strange crust that forms on your eyes when you wake up. Thank you plica semilunaris. How can we live without waking up with strange things in our eyes?
9. Arrector Pili
Arrector pili are extremely small muscle fibers that attach to every hair follicle on your body. It is known to make the hair stand up, which leads to goosebumps. Most mammals, including humans, have these small muscle fibers; but they serve no real purpose. As for animals with more fur, they are more useful because they provide a layer of insulation.
8. Wisdom teeth
These teeth were once very useful, especially when humans had a diet of very tough meat. Wisdom teeth, at this time, allowed people to chew their food properly. Nowadays, many people do not accept them at all. And if they do, they are certainly in for a surprise. Generally, wisdom teeth are removed because they are growing incorrectly or because they are causing pain.
7. Coccyx
However, the coccyx is not completely useless. This allows for the attachment of many different ligaments, tendons and muscles. It is also useful when it comes to weight loss. In any case, the coccyx is generally more important in tailed mammals.
6. Tonsils
Tonsils are another useless part of the body and can cause a lot of pain in certain people. Open your mouth wide and you'll see a tonsil on each side of your throat if you haven't removed them.
5. Adenoids
Adenoids are masses of lymphoid tissue located at the very back of the nose. However, they only provide strong protection against inhaled bacteria. As you grow older, your adenoids shrink, rendering them useless. They are only useful when you are a child.
4. Sinuses
The sinuses are a part of the body that doctors really don't know much about. We have many of them, but they are nothing more than empty spaces filled with air. Some say they insulate our eyes, while some doctors say they affect our voice and tone. In any case, no one knows exactly what they are for, but we do know that they cause headaches. Sinuses are also notorious for infections.
3. Male nipples
It doesn't need much explanation. Males don't breastfeed, so they don't need nipples. I guess they serve as decorations.
2. Gallbladder
The gallbladder is a small organ known to store bile and aid in digestion. However, the gallbladder sometimes forms gallstones, causing people to be unable to eat without vomiting. If so, it comes out.
1. Appendix
The appendix is a narrow, muscular tube that connects to the large intestine. Its purpose is to digest cellulose. When the body became more familiar with vegetables, the appendix was a more important and useful organ. Supplementation was very important when the human diet consisted mainly of plants. However, in the modern world, the appendix is not a necessary organ. About 300,000 Americans have had their appendices removed.
