Question

What is a function of the respiratory system?

Answer 1

The respiratory system's main purpose is to move fresh air into your body and moving waste gasses out (like carbon dioxide when you breathe out)

Answer 2

The function of the respiratory system is to inhale oxygen which is absorbed by red blood cells in the lungs. The RBC then go to the heart which pumps the oxygenated blood to the rest of the body and non oxygenated blood goes back to lungs to be oxygenated. They also carry back waste such as carbon dioxide to the lungs to be exhaled.
