Lesson 1
Tiny glands in your ear
Your ear canal is the tunnel that leads from the outside of your ear to your eardrum.
In the skin of the outer part of the canal are tiny coiled glands called ceruminous glands. They are a special kind of sweat gland.
Their cells line a small tube, and they let out their liquid near the little hairs in your ear.
Lesson 2
Making earwax
The liquid these cells make mixes with skin oil and old skin flakes. Together they make earwax.
- It traps dust and dirt before they get deep in your ear.
- It helps fight germs.
- It keeps the skin in your ear from getting dry and itchy.
Wow!Earwax moves out of your ear on its own! Talking and chewing help push it slowly toward the outside.
Try thisNext time you chew, gently put a finger just in front of your ear. Feel your jaw moving? That motion helps move earwax out. (Never put anything inside your ear!)
