The Air Sac (alveolus)
C Diffusion Takes Place
Taking oxygen into the lungs.
Removing carbon dioxide from the lungs
Inflammation of the linings of the bronchial tubes.
Swelling narrows breathing passage, alveoli
clogged with mucus.
Allergic reaction narrowing of
the bronchial tubes.
Walls of alveoli break down. Decreases
surface are for gas exchange – shortness of
breath, difficulty breathing, decreased
lung capacity
Normal city dwellers lung.
Note black specks throughout
indicative of carbon deposits
from pollution.
Smokers lung with
cancer.
Smokers lung with
emphysema.
Uncontrolled growth of abnormal cells in the
lungs.
Pneumonia is an infection of the lungs.
There are several different organisms that may
cause it including bacteria, viruses and fungi.
Causes Fluid and mucus to build up in the alveoli
