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.
