<prompt> Most common cause of cell Injury at level of cells?HypoxiaIschemiaCO poisoningAnemia  <response>: Hypoxia Deficiency of oxygen,which causes cell injury by reducing aerobic oxidative respiration Extremely impoant and most common cause of cell injury and cell death. Causes:- Reduced blood flow ischemia Cardiorespiratory failure Anemia or carbon monoxide poisoning or after severe blood loss Decreased oxygen-carrying capacity of the blood. Depending on the severity of the hypoxic state, cells may adapt, undergo injury, or die.
