What Happens in the Alveoli?

Answer

When you take a breath, oxygen is passed through the nostrils, through the pharynx, trachea, and into the lungs where it fills the sacs of the alveoli. Alveoli are air sacs that line the lungs formed by terminal dilation's of the bronchioles. The alveoli are responsible for removing carbon dioxide from the lungs, and accepting oxygen from the air. Without alveoli, breathing would be hazardous to your health, as your body would become toxic because of the carbon dioxide inhalation.
