Human Body Trivia

True. Some bones in the infant’s skull have not yet fused together and so the infant has more bones than a fully formed adult.
False (although you can find this "fact" in a lot of places). Dust is made up of lots of different things including animal dander, insect waste, and dirt.
No, but be honest. You just tried to, right?
Yes, the cartilage disks in your spine expand due to the lack of gravity.
An ancient form of medicine which involves making a hole in the human skull to relieve pressure. Do not do this.
In the middle ear. Collectively called ossicles, the 3 bones are the malleus (hammer), incus (anvil) & stapes (stirrup).
A substance - usually produced by bacteria - that causes fever.
It is your outer ear, the bit you see made out of cartilage.
AB negative. Less than one percent of the population has this blood type.
The eye’s lens continues to grow throughout one’s life. It becomes thicker and less transparent.
People often favour one leg over the other. It is possible that over time the discrepancy between the two leg strides may indeed cause you to walk in circles.
False. This is a common myth taught in primary schools and it the result of a mistranslated scientific paper, from German to English.
17, and it takes 43 to frown. So let's all be lazy and smile.
True. The average human adult has trillions of microorganisms living on or in them. These microorganisms actually outnumber our body’s cells 10:1. They are however, a lot smaller than our cells, which is why they only make up such a small proportion of our weight.
False. Some bacteria are bad for us, and attack us or stop our bodies functioning properly. Others don’t interact with us at all, but might live on or around us, because we’re warm or moist. Other bacteria are needed for our body to work, like the bacteria we keep in our guts that help us digest food.
6L. However, even when you take your deepest breath in or out, you only breathe about 4.8L of air. The remaining 1.2L is air that just chills in your lungs, and mixes with your next breath.
When they come back up they let out a long, slow whistle that helps them regulate their breathing. It’s called the “ocean whistle”. They can hold their breath for up to 2 minutes and dive up to 9 metres deep.
True. Overactive sweat glands (also known as hyperhidrosis, not from exercise!) can be caused by certain medications or medical conditions. Hyperhidrosis can even lead to dehydration.
3,300,000,0000 times. This of course would change if you exercised a lot, or watched a lot of scary movies.
Food As a general rule, people can survive up to 3 weeks without food, but only 3 days without water
Aorta in your chest. This is the first blood vessel the blood travels through once it leaves your heart, and carries the blood away to be distributed around your body.
True. They don’t start breathing until after they’re born, and so they don’t need air in their lungs. Once they are born they cough out the water and start breathing like you or me. For a little while after they're born, their body remembers how to survive underwater, and they can’t drown!
