How Our Lungs Help Us Breathe
Hey there! Let’s talk about our lungs and how they help us breathe. Our lungs are like two big balloons inside our chest. When we breathe in, our lungs fill up with air and get bigger, just like a balloon does when you blow it up.
Here’s how it works:
- Breathe In: When you take a deep breath in, your body sends a signal to your lungs to expand. This means they get bigger and fill up with air!
- Squeeze It Out: When you breathe out, your body tells your lungs to squeeze the air out. So it's like letting the air out of a balloon, and the lungs get smaller again.
And that’s how we breathe in air and breathe out the air we don’t need anymore! Isn't that cool? So remember, your lungs are like balloons: they get bigger when you breathe in and smaller when you breathe out!
