What is necrotic tissue?

  1. Dead cells caused by deprivation of blood supply

  2. Cells that are inflamed and swollen

  3. Cells that have undergone mitosis

  4. Healthy tissue with adequate blood flow

The correct answer is: Dead cells caused by deprivation of blood supply

Necrotic tissue refers specifically to dead cells that result from the deprivation of blood supply. When blood flow is compromised, tissues do not receive necessary nutrients and oxygen, leading to cell death. This process can occur in various conditions, such as infections, trauma, and vascular disorders. Understanding necrotic tissue is crucial in esthetics as it can affect skin health and healing processes. Recognizing necrosis and its causes is essential for professionals to provide safe and effective treatments. This knowledge helps in identifying unhealthy tissue that may require different approaches compared to healthy tissue, ultimately impacting client outcomes and safety in esthetic practices.
