What is necrosis tissue?

Necrosis tissue refers to dead cells that occur in a specific area of tissue due to a lack of blood supply, which can be caused by various factors such as injury, obstruction of blood flow, or infection. When tissues do not receive adequate blood circulation, they cannot obtain the necessary oxygen and nutrients, leading to cell death. This process typically results in the breakdown of cell structure and ultimately, the tissue itself.

Understanding the concept of necrosis is crucial in fields that deal with tissue health and healing, as necrotic tissue can lead to further complications and requires appropriate medical intervention. Recognizing necrosis allows for the differentiation between healthy and non-viable tissues, guiding treatment decisions effectively, such as the need for surgery or other therapeutic options.

The other options describe different states of tissue but do not accurately define necrosis. Healthy cells with proper blood supply, infected cells causing inflammation, and living tissue that is rejuvenating do not pertain to the concept of necrosis but rather to the normal function and condition of living tissues.
