Lungs Design And Purpose »
What are the lungs?
The lungs are a pair of organs in the chest, which are
primarily responsible for the exchange of oxygen and carbon
dioxide between the air we breathe and the
blood.
What does breathing accomplish?
The cells in the body constantly need a new supply of
oxygen to produce energy. With lack of oxygen, cellular
function is impaired and damage or cell death may occur. As
energy is utilized, waste products are created, one of
which is the gas carbon dioxide. Eliminating carbon
dioxide from the body is just as important as breathing in
oxygen from the air. If carbon dioxide builds up in the
blood it will lead to headaches, drowsiness, coma, and
eventually even death.
What is the structure of the respiratory system?
Air enters the body via the nose (preferably) or the
mouth. The air enters the main windpipe, called the
trachea, and continues en route to each lung via ...

I have had bronchitis three times in my life, twice in the last two years. The last two bouts began right before Thanksgiving and lasted until New Year's (about six weeks). This seems consistent with what I have read. ("Acute" bronchitis can last up to six weeks ...) I got better as the weeks progressed, but it took me about six weeks to get fully "well." Things that I found helpful were: Mucinex, drinking a "healthy" amount (about two liters for me) of water, and an albuterol inhaler. I have been prescribed codeine and Tessalon Perles, but these have not worked for me. The Mucinex (which is OTC) seemed to thin the mucus and decrease the coughing. Drinking water also helped. It seemed to make my cough more wet/productive (which may not seem desirable), but it also seemed to decrease the frequency and extent of my coughing fits, especially those dry ones that just won't end! My doctor prescribed the albuterol inhaler (often used for asthma) when I went to see him about the bronchitis. It seemed to help me breathe and decrease my coughing somewhat. One final note: My brother swears by Celestial Seasonings Echinacea wellness tea with a spoonful of honey. I didn't find out about this until my last bout was almost over, so I can't really comment. But he says this helps him when he has respiratory infections. Published: January 21 ::
