When pupils correctly match surfactant with, the lecturer concludes that the lesson was effective. With each breath, it prevents alveoli from collapsing.
The partial pressure between liquid phases, between an a gas and a liquid, or the interfacial tension between such a liquid and a solid can all be reduced by chemical molecules called surfactants. Cleaning products, cleaning fluids, emulsifiers, foaming agents, and dispersants are all examples of surfactants in action.
The lung cells exude surfactant, which distributes throughout the alveolar tissue. This chemical reduces surface tension, which facilitates easy breathing by preventing the collapse of the alveoli following exhalation. Surfactants are employed in lubricants, inks, pro solutions, herbicides, adhesives, emulsifiers, and fabric softeners in addition to soap and detergents.
