Bronchitis




Bronchitis is an
inflammation of the lining
of the bronchial tubes.
The bronchi become
infected and less air is
able to flow to and from
the lungs, and a heavy
mucus is coughed up.
Smoking is by far the
most common cause of
bronchitis.
Close to 9 million
Americans are diagnosed
with bronchitis annually.
Influenza





It is commonly called the flu
Generally spreads from person-to-person when an
infected person coughs or sneezes
Influenza can lead to severe illness if not treated quickly
and effectively
Symptoms include fever, dry cough, sore throat, runny
or stuffy nose, headache, muscle aches, and extreme
fatigue
Children may experience problems such as nausea,
vomiting, and diarrhea.
Sarcoidosis






It is also known as Sarcoid or Boeck’s disease
It is a multi-system auto-immune disease
It especially involves the lungs with resulting fibrosis
but can also effect the skin, liver, spleen, eyes, bones,
brain, parotid glands and other soft tissue organs.
Not contagious
It can cause lifelong ailments.
There is no cause or cure for this disease.
•Air enters through the nose and the
nose hairs block dust and unwanted
objects
The nasal passage warms
and adds moisture to
the air you breathe.
The epiglottis is a flap
that closes over the
trachea during
swallowing preventing
choking.
Esophagus
•Air also enters through the
mouth
The bronchi is
a short tube
that carries air
from the
trachea to each
lung
The diaphragm
is the muscles
at the bottom
of the chest
cavity that
enables
breathing
Bronchioles
The trachea is a
tube that carries air
from the nasal
chamber to
bronchi
The lung is the
main organ of this
system. Gas
exchange occurs
here.
The alveolus
is and air sac
where gas
exchange
occurs
between your
blood and the
air you breath
Capillaries are
blood vessels that
surround the
alveoli
The Respiratory System
Inhaling & Exhaling

Exhaling = When the
diaphragm relaxes, the
cavity inside your body
gets smaller and your
muscles squeeze your
ribcage and your lungs
begin to collapse as the air
is pushed up and out of
your body in an exhale,
which reduces the air
pressure in your lungs.

Inhaling = Inhaling
begins when the
diaphragm pulls down,
and lowers the internal air
pressure. When the air
pressure is greater outside,
you suck in the air in an
inhale, which expands
your lungs and increases
the air pressure in your
lungs.
