Death of tissues of part of the body usually due to deficient or absent blood supply is called?

• A. gangrene
• B. subcutaneous emphysema
• C. agonal edema
• D. bacterial translocation

Answer: (A)

Tissue death due to inadequate blood supply is gangrene. When blood flow drops or stops, tissues don’t receive oxygen and nutrients, and cells begin to die. Over time, the affected area can become necrotic, and gangrene may develop in forms such as dry (from ischemia alone) or wet/gas (when infection is involved). The other terms describe different conditions: subcutaneous emphysema is air trapped under the skin; agonal edema relates to swelling around the time of death; bacterial translocation is the movement of bacteria from the gut to other body sites. So the description matches gangrene.
