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 am 56 now. I was diagnosed with COPD in March of 2007. I had been a heavy smoker, got a cold I couldn't get rid of, ended up in the hospital, on a ventilator. I should have known it was coming, but like most smokers, thought it would never happen to me. I don't smoke now and never will again, but, I still want to. My life has changed drastically. I had to stop working, sold my home (couldn't afford it without a salary), and cashed in my retirement to be able to move closer to family and support. I have very little energy most days; I try to use what I do have wisely. I rest/sleep a lot. I carry tremendous guilt because I "did this to myself" and I try hard not to be a burden to my family. I was someone who rarely took even an aspirin, now medications are a huge part of my life. I finally have Medicare, but it doesn't cover prescriptions, and they are so expensive. There may soon come a time when I have to pick the most important ones and let the rest go. I use oxygen at night. I try to count my blessings, fully appreciate what I do have, and remain positive, but I'm not always successful with that. Published: January 07 ::
