Cell injury

CELL INJURY (Apoptosis,Necrosis,Gangrene) Defnition: Cell injury is the effect of stresses due to variety of etiological agents on the cell. Causes of Cell Injury 1.Hypoxia: It refers to inadequate oxygenation of tissue. Causes of hypoxia: •(a) Decreased blood flow is called ischemia. (b)• Inadequate oxygenation of the blood (hypoxemia) – Due to pulmonary disease. –…Read moreRead more
