History of Emphysema in Timeline
Emphysema is characterized by air-filled enlargements in body tissues. While it can occur in various tissues, the term "emphysema" most commonly refers to a lung condition called pulmonary emphysema. This specific type of emphysema involves the irreversible expansion of the alveoli, which are tiny air sacs in the lungs responsible for gas exchange.
