sur·fac·tant

 (sər-făk′tənt, sûr′făk′-)
n.
1. A surface-active substance.
2. A substance composed of lipoprotein that is secreted by the alveolar cells of the lung and serves to maintain the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung.

[surf(ace)-act(ive) + a(ge)nt.]

surfactant

(sɜːˈfæktənt)
n
(Chemistry) Also called: surface-active agent a substance, such as a detergent, that can reduce the surface tension of a liquid and thus allow it to foam or penetrate solids; a wetting agent
adj
(Chemistry) having the properties of a surfactant
[C20: surf(ace)-act(ive) a(ge)nt]

sur•fac•tant

(sərˈfæk tənt)

n.
any surface-active substance, as a detergent or a natural or artificial substance that coats the lungs and prevents them from collapsing.
[1945–50; surf(ace)-act(ive)a(ge)nt]

sur·fac·tant

(sər-făk′tənt)
1. A substance, such as detergent, that is added to a liquid to increase its ability to spread.
2. A substance produced by the tiny air-filled sacs of the lung that reduces the surface tension of the fluids coating the lung. Surfactant helps keep the tiny air sacs from collapsing during normal breathing.

surfactant

(surface active agent) A substance (for example a detergent) added to a liquid which can alter its spreading or wetting characteristics by lowering its surface tension.
