Introduction:
Shock is defined as the condition wherein the tissues of the body do not receive enough oxygen and nutrients. This failure of the circulatory system can be due to an obstruction in the flow of blood or blood loss. Inadequate blood supply causes the cells to swell and causes the membranes of the lysosomes to rupture.
