Imagine your blood is like a superhero that carries air. When we breathe in, the superhero grabs lots of fresh air called ‘oxygen.’ It takes this oxygen to our body parts so they can work and play.
Now, when our body parts use this oxygen, they make something called ‘carbon dioxide.’ But we don’t need that, so the superhero carries it away, like taking out the trash. When we breathe out, we’re saying bye-bye to the carbon dioxide.
So, one superhero helps us get air (oxygen) and takes away the bad stuff (carbon dioxide) so we can stay healthy and happy!” 😊🦸♂️💨
