Your body is made up of tiny cells, each of which has a special job that keeps you alive. Every cell in your body needs a special gas called oxygen, that allows the cell to get energy from the food you eat. Oxygen in the air is brought into your lungs. That's when your blood picks it up and brings it to your cells.
Another gas, called carbon dioxide is a waste product of your cells. It is very dangerous if it builds up in your body. Your blood carries the carbon dioxide from your cells to your lungs, to let you breathe out all the bad gas!
When we exercise, our cells are working harder, and they need more oxygen. They also produce more carbon dioxide. That's why you breathe faster when you exercise!
You have probably noticed that when you're exercising, your heart beats more quickly. That's so that the blood can carry oxygen to your cells faster!
Your heart and lungs work together to make sure every cell in your body gets enough oxygen.

Each time you take a breath, oxygen is supplied to the lungs. This oxygen is converted to carbon dioxide and once the carbon dioxide builds up, it prompts the body to take another breath.

Serious answer: Oxygen won't enter the body fast enough unless the lungs pull it in. Likewise, carbon dioxide won't leave the body fast enough unless it's pushed out by the lungs.
Silly answer: It's just a habit I've had since I was a kid.

Every time you breathe in, an average of ten people die.

Because if I don't...I'll pass out. You need to breathe more often. Deeply.

So the red blood cells can take the oxygen to your heart, brain, and other organs and muscles! :D
