Surfactant
Surfactant is a lipoprotein molecule which is produced by alveolar type 2 cells in the lungs. It is required in the lungs to maintain surface tension in alveolar type 1 cells. This maintenance of surface tension is key to allow the rapid diffusion of gases such as oxygen and carbon dioxide across the alveoli membrane [1]
