Chronic bronchitis is a chronic inflammation of the bronchi (medium-size airways) in the lungs. It is generally considered one of the two forms of chronic obstructive pulmonary disease (COPD), the other being emphysema. It is defined clinically as a persistent cough that produces sputum (phlegm) and mucus, for at least three months per year in two consecutive years.

Famous quotes containing the word chronic:
“What the horrors of war are, no one can imagine. They are not wounds and blood and fever, spotted and low, or dysentery, chronic and acute, cold and heat and famine. They are intoxication, drunken brutality, demoralisation and disorder on the part of the inferior ... jealousies, meanness, indifference, selfish brutality on the part of the superior.”
—Florence Nightingale (1820–1910)
