WHAT IS THE PURPOSE OF BREATHING?

You have to breathe because all of the cells in your body require oxygen. Without oxygen, your body wouldn't move. It would be like a parked car without no battery. The car might have gas, but without a battery, forget it! So you might have blood in your body, but without oxygen, forget it!
You receive oxygen from breathing in air and then the oxygen goes to your blood which is then circulated throughout your entire body. WHAT IS THE PROCESS OF BREATHING? You breathe with the help of your diaphragm (which is a dome-shaped muscle under your rib cage) and other muscles in your chest and abdomen. These muscles will literally change the space and pressure inside your body cavity to accomodate your breathing. When your diaphragm pulls down, it is making room for the lungs to expand. The lungs get bigger with air and pushes the diaphragm down. The diaphragm also lowers the internal air pressure.
