Students Should Know Facts on the Human Body

1. You have 206 bones in your body, but when you were born, you had around 300! Some of them joined together as you grew.
2. Your lungs are like big balloons that fill up with air every time you take a breath. You take about 20,000 breaths a day!
3. Fun Fact: Your skin is the largest organ in your body. If you stretched it out, it could cover about two square metres!
4. Your stomach produces a new layer of mucus every two weeks so that it doesn’t digest itself!
5. The muscles in your eyes are the busiest muscles in your body. They move more than 1,00,000 times a day!
6. Your ears never stop working, even when you’re asleep. They keep picking up sounds, but your brain ignores them so you can rest.
7. Your teeth are the only part of your body that can’t repair themselves. That’s why it’s so important to take care of them!
8. When you laugh, about 17 muscles in your face and belly get a workout. So laughing is like exercising your body!
9. Fun Fact: Your blood travels through a network of vessels so long that if they were laid end to end, they could circle the Earth twice!
10. Your heart is about the size of your fist and it beats around 100,000 times every day.
