What term describes tissue that has undergone death from a lack of blood supply?

The term that describes tissue that has undergone death due to a lack of blood supply is "necrosis." This process involves the irreversible damage and death of cells, which occurs when the tissues are deprived of oxygen and nutrients typically delivered through blood. When cells are unable to function and maintain homeostasis without adequate blood supply, they begin to break down and die.

This often happens as a result of various causes, including infections, toxins, or insufficient blood flow due to blockage or other vascular issues. The dead tissue can lead to a range of pathological conditions and may require medical intervention to prevent further complications or infection.

While other terms like ischemia, stasis, and infarction relate to the processes or conditions leading to, or resulting from, decreased blood flow, it is necrosis that specifically refers to the death of the tissue itself. In the context of the question, understanding the distinction between these terms is vital for grasping the underlying mechanisms of tissue death in pathology.
