Introduction

Oxygen is a vital gas, responsible for life on earth. It generates energy and supports the life of all the living organisms. In order to survive, all of our cells need oxygen. The complex process of getting your body the oxygen it needs is a collaborative effort among your gut, brain, bones, lungs, blood, and heart.

• Your brain initiates breathing by sending a message through your nervous system to your muscles, diaphragm, and ribs, which ultimately allows your lungs to expand.
• As you unconsciously breathe in, the air around you enters through your nose and mouth. Oxygen then is transported on red blood cells which contain oxygen-binding molecules called hemoglobin.
• Once your lungs process the oxygen, the oxygen-rich cells are carried to the cardiovascular network, a massive collection of blood vessels throughout your body. The network is so lengthy, that if stretched out, it would be able to wrap around the Earth several times.
• Lastly the heart pumps the blood cells through your body to every single cell.
