The lungs are one of six organs in the respiratory
 The other five organs include: nasal cavity,
pharynx, larynx, trachea and bronchial tubes.
The lungs are essential respiration organ
that is located in all breathing mammals.
 The lungs transport oxygen from the
atmosphere into the bloodstream.
 Then, the lungs release carbon dioxide
from the bloodstream back into the
Theoretically, there should be a right an
left lung in your chest.
 The left being smaller than the right lung
due to the fact that there is less space in
the pleural cavity because of the mass
of the heart.
 The left lung contains only 2 lobes and
the right has 3 lobes.
Each lung consist of bronchi, bronchioles
and alveoli.
Bronchi are pipes leading from the
trachea to each lung.
 Bronchioles are smaller and smaller
branches of bronchi.
 Alveoli are very little small sacs at the
ends of the smallest bronchioles where
oxygen gets into the blood and carbon
dioxide exits.
The lungs are spongy because they
contain air.
 The lungs are protected by membrane
called pleural.
Asthma: a disease the affects the lungs by
the constriction of the bronchial airways.
Can cause violent spasms of the bronchi.
Maybe caused by various allergens.
 Emphysema: a pulmonary condition that
characterized by destruction of the walls of
the alveoli resulting in fewer over expanded
air sacs. Can be caused by smoking and
sometimes the air you breathe.
Pneumonia: an inflammatory condition
of the lung that can be caused by
bacteria and viral infections, diseases,
and chemicals. Resulting in the alveoli
spaces filled with fluids.
 Tuberculosis (TB): an infectious disease
caused by bacteria. It affects the
respiratory system and causes
inflammation and calcification in the
The lung on the left is a healthy lung and
the one the right is an unhealthy lung:
