Pathology describes the abnormal or undesired conditions while pathophysiology entails explaining the physiological processes or mechanisms where such conditions develop and progress. It is a physiology of abnormal state that is normally followed by a disease or a syndrome.

Answer:
Concentration gradient means difference in solute concentration among two regions of a solution.
Explanation:
When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .
       Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.
       During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.
