It prevents a pleural friction rub. Its like a lubricant for the lungs to move up and down without any friction.
A substance that tends to reduce the surface tension of a liquid in which it is dissolved.
The main function or job of a surfactant is to reduce surface tension. This process is used on liquids while it dissolves.
Surfactant helps reduce surface tension within the alveoli, thus preventing each alveolus from callapsing as air moves in and out during respiration.
Pulmonary surfactant...see link for more information.

surfactant
Surfactant is a substance which lines the inside of alveoli. It is composed of a phospholipid bilayer, which have hydrophyllic and hydrophobic properties. This allows it to reduce surface tension.
The correct answer is Surfactant
Am pretty sure its called the pulmonary surfactant that's produced from the lungs
Surfactant reduces the surface tension within in your lungs, your alveoli have a wet surface and if surfactant were not present they would stick together causing a difficulty in expanding your thoracic cavity-so you wouldn't be able to breath without surfactant.
Surfactant! or 'Pulmonary Surfactant' Just had one of those moments too :)
The fluid lining the inner alveolar membrane is called surfactant. It helps reduce the surface tension in the alveoli, which prevents them from collapsing in on themselves every time we exhale.
