  • Evidence suggests that during ischaemia, potassium efflux through the K+-ATP channel plays a major role in the development of cardioprotection.

    Academic text (1995)

    Academic text (2000)
  • Field and laboratory measurements of CO2 efflux are indicative of low but detectable rates of respiration in dry valley soils (Burkins 1998).

    Academic text (1999)
  • The multiplicity of resistance genes, low inoculum size, variations in permeability to antibacterial drugs, and the activity of efflux pumps are factors influencing antibacterial drug sensitivity.

    Academic text (2014)
  • Glibenclamide, a specific blocker of the K+-ATP channel that decreases ischaemia-induced potassium efflux, has been shown to interfere with this cardioprotective mechanism and to increase infarct size in animals.

    Academic text (1995)

Morphology

efflux = flux (transparent) = ef + flux

Formed from ef- (out, variant of ex-) + flux (flow), so the meaning 'outflow' is directly derivable for learners familiar with the components.

Etymology

The word efflux comes from Latin parts ex- 'out' and fluere 'to flow', and you can see the same root in fluid and flow. So an efflux is simply a 'flowing out' of a substance from a place, which explains how we use the word today.
