The Breathing Process

To better understand how health hazards can enter your body by inhalation, let's take a closer look at the breathing process.

- Whenever you take a breath, oxygen rich air is      taken into your body through your mouth and nose,   goes down your windpipe and into your lungs.

- In your lungs, there are tiny air sacs called alveoli.

- These delicate air sacs then transfer the oxygen that    is in the air into your blood. At the same time the    oxygen is being absorbed into your bloodstream,    carbon dioxide is being transferred from your    bloodstream into the air sacs.

- When you breathe out, you are ridding your body of    gaseous wastes.
