In a highly compliant lung, as in emphysema, the elastic tissue is damaged by enzymes. These enzymes are secreted by leukocytes (white blood cells) in response to a variety of inhaled irritants, such as cigarette smoke. Patients with emphysema have a very high lung compliance due to the poor elastic recoil. They have extreme difficulty exhaling
This probably reflects the disorganization and perhaps loss of elastic tissue as a result of destruction of alveolar walls. Manifestations of the Disease Now in emphysema you have decreased elastic recoil (compliance) so it is like a grocery bag, inflated easy but there isn't as much pressure wanting to push air out as say a balloon. So alveolar pressure at a max breath in someone with emphysema is lower than in normal. So now when they go to expire forcefully (for say a FEV1 measurement).
17 Jun 2004 Pulmonary emphysema is a disease that is characterized, if not defined, by the destruction of lung parenchyma (1). This destruction is believed

Point, really big toes when you push off and you get that elasticity sort of wound up. And they have fibre placement, which have an awful lot of recoil. elapsing. elastic.
So now when they go to expire forcefully (for say a FEV1 measurement). The loss of elastic recoil concerning the wall of the small airways, due to the reduction of elastic tissue in the pulmonary parenchyma, is an evident mainly in emphysema. The absence of cartilage in the wall of the small peripheral airways contributes further more to the loss of the elastic recoil [ 8
The contribution of elastic recoil and the surface tension on the total elastance can be demonstrated by pressure-volume curves, determined in vitro, of lungs which are either gas-filled or liquid filled. The elastance of the gas-filled lungs can be assumed to have the same elastance as that, which is attached to the thoracic wall. Emphysema is destruction of lung parenchyma leading to loss of elastic recoil and loss of alveolar septa and radial airway traction, which increases the tendency for airway collapse. Lung hyperinflation, airflow limitation, and air trapping follow.

Elastic recoil measurement, single-breath nitrogen (SBN2) tests, and FEV1 were obtained from 18 lungs with no emphysema and 21 emphysematous lungs with no greater than Grade 5 emphysema score. The mean number of alveolar attachments per brochiole was determined from all the bronchioles cut in cross section. However, 1 to 2 percent of all cases of emphysema are linked to an inherited deficiency of alpha-1-antitrypsin, an enzyme that prevents protein breakdown. This leads to unchecked digestion of the tissues of the lungs, setting the stage for emphysema.

L U N G intercostal muscle contraction, followed by passive recoil of the lung during Emphysema may occur rarely; however this is predominantly of the distensive In emphysema, loss of lung elastic recoil results from damage to elastic fibers and loss of alveolar surface area. An increase in bronchial airflow resistance is another sentinel feature of lung mechanics in COPD.
