Pulmonary Arterial Hypertension in Older Adults: An Update
نویسندگان
چکیده
The bronchi are inflamed and mucous cells lining the airway increase in number and excretion rate. The bronchial passageways become narrower and airflow to the alveoli decreases. The cells lining the bronchi are continuously inflamed and the mucous cannot be efficiently removed and eventually builds up within the airways. If the mucous is not removed, bacteria will remain in the lower airways and increase the possibility of an infection.
