Different parts of the brain are responsible for different things, like thinking, feeling, moving, and breathing, and they work together all the time.

Your body has enough iron to make a small nail.

Your blood is blue before it gets oxygen.
π‘ Explanation
False! Your blood is always red, no matter how much oxygen it has. When blood has little oxygen, it's dark red, almost a reddish-brown. When it has lots of oxygen, it's bright and clear red. The veins we see through our skin can look bluish, but that's because of how light reflects through the skin, not because of the blood's color.

Your hair and nails are alive.
π‘ Explanation

The blood in your veins is blue.
π‘ Explanation
False! Blood is always red. When blood has lots of oxygen, it's bright red. When it has less oxygen, it's dark red. Your veins look blue because the light shining through your skin makes them appear blue to our eyes, not because your blood is actually blue.

Your tongue is the strongest muscle in your body.
π‘ Explanation
That's a common misunderstanding, but it's false! Your tongue is incredibly flexible and enduring, but it's not the strongest muscle. Different muscles are strongest depending on how you measure. The jaw muscle (masseter) can exert the most force when you bite. Your thigh and butt muscles are stronger when it comes to lifting heavy things or jumping.

Your eyes see things upside down.

Your brain can feel pain just like the rest of your body.
π‘ Explanation
False! It might sound strange, but your brain actually can't feel pain. The brain tissue itself doesn't have any pain receptors. Instead, the brain is what receives and understands pain signals from *other* parts of your body. So, if you bump your knee, your brain tells you it hurts, but the brain itself can't feel pain!

Humans only use 10% of their brain.
π‘ Explanation
That's a common myth! We actually use almost our entire brain, even when we're sleeping. Different parts of the brain are active at different times so we can think, feel, move, and learn new things. No part is useless, and the brain is always busy!
