Inadequate circulation of blood through out the body is referred to as shock or hypoperfusion. Adequate supply of blood to body tissues is important as it supplies oxygen and nutrients and collect waste materials from the tissues. Limited/ inadequate supply of blood to various organ tissues such as the legs, hands, heart and rest of the body, including the fingers may cause a shock. Inadequate supply of blood mainly results from the blockage of blood vessels by the build up of fatty substance (plaque) in the vessels causing hardening and constriction of the wall of veins and arteries.
