COPD is characterized by aveolar destruction. Funstional alveoli are necessary for the transport of oxygen from the atmosphere into the blood stream and eventually to the tissues. Loss of alveoli equals loss of oxygen in the tissues and incidently increase in carbon dioxide in the same since it cannot be excreted into the lungs. The end consumer of oxygen is the target tissue. The tissue merely registers that oxygen levels are low, but cannot differentiate as to whether they are low for lack of oxygen transport capacity or lack of oxygen to be transported. Hemoglobin is a molecule that binds oxygen in the bloodstream. It is responsible for the delivery of a majority of the oxygen that reaches the target tissue. Since an organism is not necessarily able to alter the external environment that it is in, i.e. the oxygen that is available to it, it attempts to increase it's ability to transport the oxygen that is available, i.e., it increases the concentration of hemoglobin in it's bloodstream. Hope that this helps. PTR
The scientific name for chronic obstructive pulmonary disease is COPD.
Chronic obstructive pulmonary disease (COPD) is also known as chronic obstructive lung disease (COLD), chronic obstructive airway disease (COAD),chronic airflow limitation (CAL) and chronic obstructive respiratory disease (CORD).
COPD is an acronym for the disease called Chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease is a lung disease that, unfortunately, at the moment, has no cure.

If you start to notice constant coughing, shortness of breath, and wheezing, it may be chronic obstructive pulmonary disease. This cough is likely to not be a dry cough.

It's a garbage-pail lung disease term meaning "Chronic Obstructive Pulmonary Disease".(COPD)-Chronic Obstructive Pulmonary Disease COPD includes emphysema and chronic bronchitis. Most COPD patients have both. • In Chronic Bronchitis, airflow may be limited by narrowed airways that get tight, swollen, and filled with mucus. These changes limit airflow into and out of the lungs. • In Emphysema, the tiny air sacs (alveoli) in your lungs are damaged. Like old balloons, they get overstretched. They break down. Old air gets trapped in the air sacs. So there's no room for new air to get in.Its Chronic Obstructive Pulmonary Disease also known as Chronic Obstructive Lung Disease.
