The respiratory system is super important for our bodies because it helps us breathe! When we inhale, air goes into our lungs, and we take in oxygen, which our bodies need to work properly. The lungs are like big bags that fill up with air, and they have tiny little sacs called alveoli, where the oxygen gets absorbed into our blood. Then, when we exhale, we push out carbon dioxide, which is a waste gas our bodies don’t need. So, the respiratory system is all about getting oxygen in and getting carbon dioxide out, keeping us alive and active!
make me a short paragraph about the respiratory system (make it like a 7th grader wrote it)
