Krogh length

Short description: Distance nutrients diffuse between capillaries

The Krogh Length, λK, is the distance to which nutrients diffuse between capillaries, based on cellular consumption of the nutrients.[1][2]

It can be described as:

λK=Dsco/R

where Ds is the diffusion constant of the solute in the substrate, co is the concentration in the channel, and R is the consumption by the cells. Units are in terms of length.[citation needed]
