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 Boecks 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

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.
