varicose veins for years without ulceration)] Ulceration is caused by hypoxia‚ which is a decrease in the amount of oxygen reaching the tissues. Limiting the amount of oxygen can cause ulceration from minor trauma from the decreased capability of the body to respond to cellular demand. Ulceration can also be caused by the increased vascular permeability causing fibrin to adhere to the capillary walls. The barrier can also cause hypoxia. The increase in blood flow from venous htn triggers an inflammatory

various intracellular organelles‚ such as mitochondria and the cytoskeleton‚ may also show alterations. Causes of Cell Injury Oxygen Deprivation. Hypoxia is a deficiency of oxygen‚ which causes cell injury by reducing aerobic oxidative respiration. Hypoxia is an extremely important and common cause of cell injury and cell death. Causes of hypoxia include ischemia‚ cardiorespiratory failure‚ and decreased oxygen-carrying capacity of the blood‚ after severe blood loss. Depending on the severity
