Bones are very important. Adults have 206 bones, while babies start with about 300.

When you spin, fluid moves around inside your ear. When you stop, the fluid keeps moving. Because the fluid is still moving, you get dizzy.
No, not that heart! The one inside your body?
Yep, that one! Your heart is an organ. That means it's a soft part of your body. It pumps blood all day! It's also very important. Without it, you would die.
Hair is used like our coat, or hat. We have an adverage of 127,000 hairs, though about 50-75 fall off each day.
