Understanding lung growth and development is critical for understanding normal pulmonary physiology as well as the developmental basis for the pathogenesis of pediatric respiratory disease. The primary function of lungs is gas exchange. Gas exchange occurs through development of lung parenchyma into millions of alveoli in close coordination with capillaries. Disruption of this developmental pathway can result in congenital lung lesions or impaired lung function.
