9 Unusual Facts about the Human Body ...

The human body is the most incredible piece of biological engineering and we know all the basics (I hope), so why not let’s uncover some of the unusual facts about the human body? I’ve read lots in researching this article and there really are some very interesting, unusual facts about the human body. Here are the ones I’ve picked to share with you.

1. Full of Eggs That Never Make It

(Your reaction) Thank you!

I presume you all know that a woman is born with all her eggs. Did you know that a woman has around 500,000 eggs in her when she hits puberty? Very few of them will ever see the uterus during a period cycle, which is one of the less well-known facts about the human body. The eggs within the woman’s ovaries are also responsible for the stimulation of the female hormone known as estrogen.

2. You Have More Bones as a Baby

(Your reaction) Thank you!

As an adult, you should have 206 bones. That includes the biggest bone, which is in your leg and called the femur, and the smallest bones that are in your ear. As a baby, you have 350 bones and they are spongy and flexible. If they were not, then it would be impossible to push a baby out. As the baby grows, its bones fuse until there are only 206 left.

3. Female Hair is Not as round as Male Hair

(Your reaction) Thank you!

The hair on a woman’s body is half the diameter of that of men. That is why it is so much easier to see on a man than it is on a woman. For some women, this is also true of hair on the head.

4. The Vagina is Full of Acid

(Your reaction) Thank you!

That’s got to be one of the weirdest sounding unusual facts about the human body, no? It is actually 4.5 on the pH scale, which is acidic but not as dangerous as you may think. Vinegar is around 2 or 3 on the PH scale. The vagina is acidic because the bacteria lactobacillus produces it as waste. It keeps nastier bacteria away. Human sperm is slightly alkali to neutralize the acid. The neutralization process also causes a little bit of heat.

5. The Fastest Muscles Make You Blink

(Your reaction) Thank you!

Your eyelids hold the fastest muscles in your body. They act so quickly that they are able to make you blink in less than a second. They are also quite enduring, as you blink thousands of times per day.

6. Your Small Intestine is Very Long

(Your reaction) Thank you!

This is one of the more well-known unusual facts about the human body. It is four times as long as you, which means it is probably between 18 to 23 feet long. It has to loop in and around your abdominal cavity like a twisted garden hose, otherwise it would not fit in your body.

7. A Part of Your Eye Breaths on Its Own

(Your reaction) Thank you!

Your cornea is the only living part of your body that does not get air from your blood. It absorbs oxygen directly from the air and gets no oxygen from your blood at all.

8. Amen to the Hymen

(Your reaction) Thank you!

The hymen is the small piece of skin that covers the ring of the vaginal opening. Most people believe that a hymen intact means that the person is still a virgin, and it is commonly quoted as one of many true facts about the human body. But a hymen is able to stretch quite a bit, which is means it is a poor indication of virginity. Its absence may only be assured if the woman has given birth. On the other hand, it is possible to tear or rip the hymen doing regular activities from riding a horse or motorcycle, and even through strenuous exercise. All of this makes the hymen a very poor indicator of virginity. On average, with one in every 2000 births, the midwife or doctor has to rip the hymen in order to allow the baby to leave more easily.

9. Your Blood Has a Long Way to Go

(Your reaction) Thank you!

You have 60,000 miles of blood vessels in your body right now, and your heart is responsible for pumping 2,000 gallons of blood through your veins and arteries every day. Wow!

Which of these unusual facts about the human body did you already know? Do you have any more you’d like to share?
