What are the 3 parts of the breathing process?

In: Health [Edit categories]

Answer:

1. Inhalation

2. Oxygen/Carbon Dioxide Exchange

3. Exhalation

1. The breathing process begins when you breathe in air through your nose, and into your lungs. When this happens your lungs expand and cause the muscle called the diaphragm to contract and go down. When this causes pressure to build up in your chest and the oxygen that you breathe in passes through the lungs and into the arteries and the red blood cells carry the oxygen all over your body. The tissue in your body uses the oxygen for heat and energy and then burns it like a fuel.

2. After the tissue uses the fuel it then turns into carbon dioxide and is carried back to the lungs by the veins.

3. When the carbon dioxide reaches the lungs and the lungs are as full of air as they can hold you begin to exhale or breathe out. The carbon dioxide is blown back out of the lungs through the nose and mouth.
