Respiratory - Surface Tension and Surfactant in Alveoli

Explore the intricate relationship between surface tension and surfactant in alveoli in this comprehensive 47-minute lecture. Delve into the significance of air-water interactions within lung alveoli and their impact on alveolar wall tension and collapsing pressure. Examine Laplace's law and alveolar histology through detailed diagrams. Understand the crucial role of surfactant in naturally decreasing surface tension and its implications for respiratory function. Learn about infant respiratory distress syndrome as a pathological consequence of high surface tension and low surfactant production. Gain insights into key concepts such as alveoli pores, surfactant production, and secretion processes to enhance your understanding of respiratory physiology.
