What are Boogers?
I Know! I Know! They are my Friends!
Oh AumSum!
In order to understand Boogers, we need to first learn about mucus. Mucus is the slimy, sticky substance which is produced by tissues in our nose, mouth, sinuses, throat as well as our digestive tract.
Mucus helps catch harmful viruses, dirt, germs and pollen and thus protects our lungs.
Tiny hairs inside our nose called cilia move the mucus along with the trapped stuff towards the front of our nose. Now when we sneeze or blow our nose, the mucus comes out. If some mucus along with the debris remains in the nose, then it starts to dry out and clumps together and finally becomes a Booger.
