Snot

Snot is a slimy substance that comes out of our noses when we are sick. It is made up of mucus and sometimes has white, yellow, or greenish colors. It is made up of dead skin cells, bacteria, and other particles, and helps protect us from germs. It’s normal to have a bit of snot in our noses, but when we are sick, our bodies make more of it to help fight off the sickness. That’s why when we have a cold, we often find ourselves blowing our noses more than usual. An analogy that might help you understand snot better is to think of it like a shield. Just like a shield protects a knight from attack, snot helps protect us from germs and other dangerous particles in the air. Fun fact: The average person produces about a liter of snot every day!
