Lung Disease
- Pulmonary Fibrosis
- Scar tissue forms on the
epithelium of the lungs,
become irreversibly
thickened.
- Therefore, diffusion pathway is
increased, oxygen cannot diffuse
as efficiently.
- Therefore, diffusion pathway is
increased, oxygen cannot diffuse
as efficiently.
- Reduces elasticity
of the lung.
- Makes it difficult
to breathe,
therefore
ventilate the
lungs
- Makes it difficult
to breathe,
therefore
ventilate the
lungs
- Shortness of breath
- Chronic dry cough-
Bodies reaction to
the obstruction of
the fibrous tissue
- Pain and discomfort
in chest
- Weakness and fatigue
- Weakness and fatigue
- Pain and discomfort
in chest
- Chronic dry cough-
Bodies reaction to
the obstruction of
the fibrous tissue
- Scar tissue forms on the
epithelium of the lungs,
become irreversibly
thickened.
- Asthma
- Localised allergic
reaction
- Air pollutants/exercise/infecction
causes white blood cells on the
linings of the bronchi to release
histamine
- Air pollutants/exercise/infecction
causes white blood cells on the
linings of the bronchi to release
histamine
- Linings of airways
becomes inflamed
- Cells on epithelial
lining secrete large
quantities of mucus.
- Fluid leaves capillaries and
enters the airways
- Muscles surrounding the bronchioles contracts,
constricting airways
- Muscles surrounding the bronchioles contracts,
constricting airways
- Fluid leaves capillaries and
enters the airways
- Cells on epithelial
lining secrete large
quantities of mucus.
- Overall, much greater
resistance to the flow of air in
and out.
- Difficult to ventilate and therefore
maintain the diffusion gradient
across the exchange surface.
- Wheezing sound when breathing.
- Tight feeling in chest
- Coughing in response to obstructed bronchi
- Coughing in response to obstructed bronchi
- Tight feeling in chest
- Wheezing sound when breathing.
- Difficult to ventilate and therefore
maintain the diffusion gradient
across the exchange surface.
- Localised allergic
reaction
- Emphysema
- Elastin in lungs
has become
permanently
stretched
- Lungs are no longer
able to force out all
the air from the
alveoli.
- Lungs are no longer
able to force out all
the air from the
alveoli.
- Surface area
of the alveoli
is reduced and
sometimes
bursts.
- Little, if any, exchange of
gases can take place
across the damaged and
stretched air sacs.
- Little, if any, exchange of
gases can take place
across the damaged and
stretched air sacs.
- Shortness of
breath, difficulty
inhaling air
- Chronic cough, body tries
to remove damaged tissue
and mucus
- Bluish
skin
coloration,
low levels
of oxygen
- Bluish
skin
coloration,
low levels
of oxygen
- Chronic cough, body tries
to remove damaged tissue
and mucus
- Elastin in lungs
