Pathophysiology clogged airways.. Bronchospasm

The mechanism of bronchial obstruction in these diseases is multifaceted. This does not prevent a particular mechanism from playing a major role in a patient alone.
Airflow in the lungs is directly and directly proportional to air pressure pressure and reverse with resistance to airway.
The actual impulse pressure during most forced exhalation is due to the elastic recoil of the pulmonary tissue.
The lack of elasticity, such as pulmonary emphysema, leads to a decrease in maximal sphincter flow. The lack of elasticity increases the resistance of the airways.
The flexible reflex is practiced in all directions on the bronchial tubes, which limits its dynamic pressure during exhalation.
A second reason for increased resistance to airways is bronchospasm. The bronchial sphincter is surrounded by the bronchial sphincter muscle of the broad amygdala (Adrenergic) and the cholinergic counterpart.
