A gangrene condition indicates what regarding tissue?

Gangrene is a serious condition that arises when a considerable amount of body tissue dies due to a lack of blood flow or an overwhelming bacterial infection. The correct choice indicates that the tissue is dead, which aligns with the medical definition of gangrene. This dead tissue can lead to a range of complications, including infection and systemic illness.

In contrast, inflammation indicates a response to injury or infection and does not signify tissue death. Bruising reflects localized bleeding under the skin and is not synonymous with gangrene. Healing tissue involves a regeneration process that occurs when there is no tissue death. Therefore, understanding that gangrene is explicitly defined by the presence of dead tissue is crucial for recognizing its implications in wound care and patient management.
