Human life depends on our bodies ability to process oxygen to keep our cells alive.

It's the circulatory system that provides every cell in our body with the juice they need to function. The human body can only survive about three minutes without oxygen, and it's this incredibly vast network that is responsible for delivering this life-giving gas to all 40 trillion cells in the body.
