The respiratory system is essential for breathing. When we inhale, air enters our lungs, allowing us to take in oxygen, which our bodies need to function. The lungs contain tiny sacs called alveoli, where oxygen is absorbed into the blood. When we exhale, we remove carbon dioxide, a waste gas. Essentially, the respiratory system helps us get oxygen in and carbon dioxide out, keeping us alive and active.
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 it shorter)

The respiratory system is vital for breathing. It allows us to inhale oxygen into our lungs, where it's absorbed into the blood, and exhale carbon dioxide, a waste gas. This process keeps us alive and active.
