Detailed explanation-1: -When a surfactant is introduced into a liquid, their molecules migrate to the surface, which creates a layer of weakly attracted molecules, leading to a decrease in the surface tension. Once the air–liquid interface is saturated with surfactant, the molecules accumulate in the bulk of the solution and form micelles.
Detailed explanation-2: -Pulmonary surfactant reduces the surface tension at the air-liquid interface throughout the lung by forming a lining layer between the aqueous airway liquid and the inspired air.
Detailed explanation-3: -Surfactants lower surface and interfacial tension by adsorbing to the surface or interface. In general, surfactants are amphiphilic molecules, meaning they have both hydrophobic (water-fearing) and hydrophilic (water-loving) components.
