Why do you breath slower when you are at rest?

When you are at rest, or sleeping, your heart beats slower. Because it is beating slower, blood travels more slowly through your body, and therefore more slowly through your lungs. As a result, you breath slower. When you do vigorous activity, your heart beats faster to supply blood to your body cells faster. This causes blood to race through your body and lungs, requiring you to breath a lot faster to keep up with the amount of blood that needs oxygen from your lungs.
