Death

Death is manifestated as the cessation of respiration and heart-beat caused by physiologec dysfunction, generally related to an illness or trauma that overwhelms the compensatory mechanisms of the body. Direct causes of death include respiratory failure (PCO2 accumulation an PO2 deficit) and hypovolemic, septic, or cardiogenic shock manifested as inadequate blood flow to the tissues depribes cells of their source of oxygen and biochemical exchange-the ultimate factor in their death.
