What is referred to as tissue death due to lack of blood supply?

The term that refers to tissue death due to a lack of blood supply is necrosis. Necrosis encompasses the death of cells or tissue resulting from inadequate blood flow, leading to oxygen deprivation and subsequent cellular damage. It is a broad term that includes various forms of tissue death, caused by multiple factors, including ischemia.

Avascular necrosis is a specific type of necrosis that occurs when the blood supply to a bone is disrupted, leading to bone tissue death. This condition often results from certain medical conditions, prolonged use of steroids, or injury. While closely related to the question, avascular necrosis is specific to bone and emphasizes the importance of blood flow in maintaining bone health.

Ischemia refers to a reduced blood supply to tissue, which can lead to necrosis if not resolved. While ischemia itself does not directly mean tissue death, it sets the stage for necrosis to occur if the blood supply is not restored in time.

Inflammation is a response to injury or infection and involves various biological processes, but is not synonymous with tissue death. It may coexist with necrotic tissue, but it primarily signifies the body's effort to heal and protect.
