0 a substance that reduces the surface tension of a liquid (= the natural force existing in a liquid that holds its surface together): --
Surfactants are used, for example, as emulsifiers or in detergents.
It is becoming more apparent that alveolar epithelial cells have functions other than gas exchange and pulmonary surfactant production.
There are several mechanisms which determine the distribution of interfacial surfactants.
Before we carry out a perturbation analysis of the surfactant equations, we shall examine the momentum equation in the static cap region.
Increased expression of pulmonary surfactant proteins in oxygen-exposed rats.
All these models neglect fluid motion and thus surfactant transport by convection.
We finally note here that if surfactants are present, the interface will be tangentially immobile independently of the viscosity ratio.
We found only a trace of surfactant in the lumen of alveoli.
A candidate might be the variation of agar surface tension along the envelope due to some surfactant secreted by the bacteria.
