ALVEOLI:\n The alveoli are the final branchings of the respiratory tree and perform gas exchange for the lung. The thin gas-blood barrier between the alveolar space and the pulmonary capillaries allows for rapid gas exchange. Oxygen and carbon dioxide diffuses through the alveolar epithelium and the capillary endothelium.\n\nThere are two types of alveolar epithelial cells. Type I cells thinly line the alveolar walls. Type II cells produce surfactant - a lubricant that reduces surface tension. \n\nSURFACTANT:\n Surfactant is any substance that acts to alter surface tensions, such as those in the lungs. This substance reduces the surface tension within the alveoli, preventing them from collapsing.\n\nInfant Respiratory Distress Syndrome is caused by a lack of pulmonary surfactant. The alveoli collapse and prevent the infant from breathing properly.
