<span>Blood vessels are dilated to increase the amount of oxygen carried in the blood, and the lungs work harder to meet the body's oxygen demands.
Blood volume increases during exercise, making the body more efficient, so it is not necessary for the lungs to work as hard.
The lungs determine the speed at which the heart pumps, so blood flows at a level that accommodates oxygen absorption in the muscles.
The lungs expand and contract, which increases the rate of blood flow so the muscles can

COPD, or Chronic Obstructive Pulmonary Disease, pretty much says it all. In COPD the Bronchioles (the pathways of air to the Aveoli), become inflamed and are occluded by mucus, because the Cilia which are responsible for pushing it out of the tract have been damaged. Because of the narrowing, the Aveoli attempt to increase the surface area so that more oxygen can be absorbed by the lungs, however this can lead to a problem as the dead space (space that is not the aveoli and can be absorbed) is then expanded as well, which leads to shortness of breath.
