Pulmonary surfactant phospholipids form monolayers and multilayers that reduce surface tension in the alveolus to negligible levels, thereby stabilizing the alveoli and maintaining lung volumes at ...

Type 2 alveoli cells are smaller and responsible for producing the substance (a “surfactant”) that coats the inside surface of the alveolus and helps reduce surface tension.

Pulmonary surfactant is a lipoprotein complex that consists of a variety of lipids -- primarily phospholipids -- and several proteins. The function of surfactant is to prevent lung collapse ...

This is specific to the tiny sacs of the alveoli. Small and fragile, they rely on a substance known as a surfactant to provide the surface tension needed to keep them from collapsing when we exhale.

It makes breathing easier and prevents the lung’s tiny air sacs, known as alveoli, from collapsing after exhalation. ... The surface tension in this case is 25 millinewtons per metre. “That’s pretty ...

Another factor in lung elasticity is surface tension. This is specific to the tiny sacs of the alveoli. Small and fragile, they rely on a substance known as a surfactant to provide the surface ...
