4. Goosebumps Are Present For One Cool Reason

You know how when you get scared or find something to be amazing you’ll experience goosebumps? They usually pop up on your arms more than anywhere else. We at times will have different feelings that result in our body reacting this way, which leads to goosebumps coming about. However, when researching into things major organs do that we weren’t aware of, we came across the reason goosebumps exist.

Since skin is an organ, we found goosebumps to be compelling for human skin to experience. Our early ancestors had them to help battle the cold for their skin. During that time, they had far more hair on their body and the goosebumps would formulate the hair to a proper spot on their bodies to warm them up. This is a similar reason you might get something known as “chill bumps” on your arms when you’re cold too.

3. The Liver Can Come Back From The Dead

The human liver is one of the most unique organs we have. While we can live without part of it, one of the coolest things about it is that it does so much for us. The liver performs a little over 500 functions for the human body, so its importance of it cannot possibly be overlooked. It seems something out there knew how important the liver would be for humanity.

Thus, we were given an amazing organ. The liver stores glucose, as well as creates bile, detoxifies the blood, produces antibodies, recycles hormones, and so much more. On top of this, it has the ability to grow back almost completely. That’s right, your liver can actually regenerate if part of it is damaged or removed. There are a lot of things major organs can do for the body, but no other organ can regenerate.

2. Your Appendix Actually Does Something Incredibly Useful

For centuries, when it came to the appendix, we always thought it was useless to us. In fact, the appendix burst in people and ended up killing them as a result of the poison released into the body. For an organ to be useless yet possibly dangerous to us made most wonder why we never evolved to just not have it. Every organ plays a huge part in the body’s function, so why did we have this thing?

In just the last decade, we were able to find out. The appendix actually helps in the immune system, however, its most important role is the storing of good bacteria. This good bacteria helps to maintain proper gut flora, which is needed heavily for the efficient digesting of food. As mentioned above, proper gut flora also offers better moods. Your appendix helps more than you thought, huh?

1. Your Major Organs Can Do So Much, You Don’t Always Need Them

It may seem kind of weird to believe but your organs are so incredible that you do not actually need them all to technically live. It might be problematic health-wise eventually, but it is possible. We know you can live without one kidney, without part of your liver, without part of your intestines, without a lot of your stomach, without your testicles/ovaries, and so much more.

The rest of the body can make up for the lost parts by merely adapting to the loss. They are all so amazing that losing large chunks of some or others completely just won’t matter. It’s like having a team of the best players in one sport on the same team. All are great to have but you could lose a few and still be successful as a team. Your body is literally made up of a dream team of organs.
