10 Oct 12 Incredible Body Parts And Functions You Never Knew Even Existed

The human body is amazing. Not only can it survive through unthinkable turmoil, but it also has thousands of functions simultaneously cooperating with each other in order to keep our bodies running smoothly at all times.

However, what’s even more spectacular about our bodies is that they’re a total mystery, and constantly allow us to delve into the unknown. There are a wealth of vessels and organs lying beneath our skin that we never knew existed, and some that even scientists hadn’t discovered until as recently as 2017!

Here are 12 incredible body parts and functions you had no idea existed.

1. Male breast milk

You may, at some point in your life, have wondered why men have nipples if they’re unable to breastfeed. In fact, this is a question that many scientists have struggled to answer themselves. Well, it turns out that every male human also has mammary glands! The thing is, the tissue inside the glands is usually so little that it has no real function. However, a very small minority of men have gynecomastia, a condition which leads to men developing very large mammary glands. This can go on to cause lactation in men.

2. The vas deferens

The vas deferens is a tiny little tube beside the testicles. It carries sperm from the epididymis to the ejaculatory duct; in other words, it allows semen to be released when a man orgasms. It’s an incredibly important part of the male reproductive system, yet so few people know of its existence.

3. The stapedius

The stapedius is the smallest muscle in the human body, and it controls the stapes which sends vibrations to our brains. Without the stapedius, we would be overwhelmed by these vibrations and everything we hear would be excessively loud.
