The fundamental concept is very simple. The basic cause of surface tension is downward pull on the surface water molecules. Surfactants molecules are made in such a way that there is no downward pull on them. Also they decrease the downward pull on nearby water molecules. This results in reduced surface tension. • 🎞More videos on Respiratory Physiology: • ● Transport of Gases • Oxygen Hemoglobin Dissociation Curve: • Oxygen Hemoglobin Dissociation Curve • Factors Shifting Oxygen Hemoglobin Dissociation Curve: • Factors Shifting Oxygen Hemoglobin Di... • Oxygen Hemoglobin Dissociation Curve during Exercise: • Oxygen Hemoglobin Dissociation Curve ... • Transport Of Carbon Dioxide: • Transport of Carbon Dioxide in blood • Carbon Dioxide Dissociation Curve: • Carbon Dioxide Dissociation Curve • Haldane Effect: • Haldane Effect in Transport of Carbon... • ● Lung Mechanics • Alveolar Pressure and Pleural Pressure: • Alveolar Pressure and Pleural Pressure • Surface Tension in Lung Alveoli: • Surface Tension in Lung Alveoli • Surfactants Mechanism of Action: • Surfactants Mechanism of Action • Functions of Surfactants: • Functions of Surfactants in Alveoli • Compliance of Lungs: • Compliance of Lungs • Diseases Affecting Lung Compliance: • Diseases Affecting Lung Compliance • • Ventilation Dead Spaces in Respiratory Tract: • Ventilation Dead Spaces in Respirat... • • Lung Volumes and Capacities: • Lung volumes and capacities • • What Determines Lung Volume?: • What Determines Lung Volume? • ● Follow me at: • • Facebook: / nonstopneuron • • Instagram: / nonstopneuron • 00:00 Introduction • 00:15 Structure of Surfactant Molecule • 00:47 Surface Tension • 01:33 Mechanism of Action of Surfactant • DISCLAIMER: This video is for education purpose only.
