Final answer:
Edema is a complication caused by blood leaking into the tissues due to increased pressure in the capillaries. It can occur in conditions such as hemorrhagic stroke, injury, and disorders of the cardiovascular system.

Edema is the accumulation of excess tissue fluid due to increased pressure in the capillaries, which promotes the flow of fluids out of the capillaries and into the interstitial fluid. This can occur in various conditions, including hemorrhagic stroke, injury, and disorders of the cardiovascular system.
