The type 2 cells of the alveoli produce surfactant, which reduces surface tension to keep the alveoli open for gas exchange. What does type II alveolar cells do? Four major functions have been attributed to alveolar type II cells: (1) synthesis and secretion of surfactant; (2) xenobiotic metabolism; (3) transepithelialRead More →

At the end of inspiration, the alveolar pressure returns to atmospheric pressure (zero cmH2O). During exhalation, the opposite change occurs. The lung alveoli collapse before air is expelled from them. The alveolar pressure rises to about +1 cmH2O. Is alveolar pressure always positive? Under physiological conditions the transpulmonary pressure isRead More →

Surfactant is synthesized and secreted by Type II alveolar epithelial cells, also called pneumocytes, which differentiate between 24 and 34 weeks of gestation in the human. What do alveolar type 2 cells do? Four major functions have been attributed to alveolar type II cells: (1) synthesis and secretion of surfactant;Read More →
