breath
Definition
Breath is the air that we breathe in and out. We need breath to live because it brings oxygen into our bodies.
Oxygen is needed for our cells to function.
When we breathe in, our lungs fill with air. The air then travels to our blood, where the oxygen is absorbed. The blood then carries the oxygen to our cells.
When we breathe out, we exhale the carbon dioxide that our cells have produced.
