Airflow from the lungs becomes restricted due to the chronic inflammatory lung illness known as chronic obstructive pulmonary disease (COPD). The signs and symptoms include wheezing, coughing up mucus (sputum), and difficulty breathing.
Inflammation of the bronchial tubes' lining, which transport air to and from the lungs' air sacs (alveoli), characterizes chronic bronchitis. Daily coughing and mucus (sputum) production are its defining symptoms.
