In normal breathing, air is sucked through >> << bronchial tract and down into finer

network of tubes in the lungs is called

, which many millions of tiny sacs surrounded by capillaries. They absorb the

and pass it. When toxins such as

smoke when inhaled into the lungs, particles caught in the trap and get

localized response. Chemicals that are allocated during the inflammatory response (eg,

) can destroy the walls of the alveoli >> << (). This is an important pathogenic event (break wall) results

significant, purely mechanical modifications easily

architecture due to lung elastic recoil which causes parenchyma collapse

partitions divide the region and holds vnutrilehochnoho air

collection that exceeds the area of ​​the alveoli, made in connection >> << to break walls. Since the process is the expansion of the chest (barrel chest

) and diaphragm contraction (flattening) is an increase in inspiratory

reexpansion / ventilation residual partially collapsed healthy
