  Wound healing is an intricate process that involves many types of cells,
reaction pathways as well as chemical, physical and electrical cues. Since
biochemical reactions and physiological events are pH-dependent we study here
pH as an important major characteristic of the wound healing process in the
presence of endogenous and exogenous electric fields. Our model gives the
spatial pH distribution in a wound. In particular we isolate a number of
dimensionless quantities which sets the length, energy and time scales
governing the wound healing process and which can be experimentally tested.
Most interesting finding is that wound pH depends on actual wound size.
