Lung Membrane

Definition: The lung membrane, also known as the pulmonary membrane or respiratory membrane, refers to the thin layer of tissue that separates the alveoli (air sacs) in the lungs from the surrounding blood vessels. This membrane allows for efficient gas exchange, enabling oxygen to pass from the air into the bloodstream, and carbon dioxide to be expelled from the bloodstream into the air.

Examples:

• The lung membrane is only a few micrometers thick, ensuring a short distance for the diffusion of gases.
• In illnesses like pneumonia, the lung membrane may become inflamed, leading to respiratory difficulties.
• The permeability of the lung membrane allows for the efficient exchange of oxygen and carbon dioxide during respiration.
