Step-by-step explanation:
The abbreviated term for the chronic lung disorder where exhaled air is obstructed is a) COPD, which stands for Chronic Obstructive Pulmonary Disease.
COPD is characterized by a long-term poor airflow as a result of a breakdown of connective tissues in the lungs.
This breakdown leads to a reduction in the number and elasticity of the alveoli, causing air to become trapped in the lungs and making it challenging for the patient to fully exhale, thus obstructing the airflow.
Smoking is the primary cause of COPD, and while there is no cure, ceasing smoking can slow its progression.
