= Krogh length
{wiki=Krogh_length}
The Krogh length is a concept from physiology and biophysics that refers to the distance over which oxygen (or other gases) can diffuse in tissues before it is consumed by cellular metabolism. It represents the effective diffusion distance of a substance in a tissue, mainly depending on the tissue's metabolic activity and the structure of the vascular system. In the context of oxygen diffusion, it is typically considered to be around 100-200 micrometers in skeletal muscle tissues of mammals.
