What is the term for the loss of blood supply to tissue?

The term that describes the loss of blood supply to tissue is ischemia. This condition occurs when there is a reduction in blood flow, which can lead to tissue damage due to a lack of oxygen and nutrients that are normally delivered by the blood. Ischemia can result from various factors, such as blockages in blood vessels or constriction of the vasculature, and can happen in various organs throughout the body.

In contrast, while necrosis refers to the death of tissue, it can occur as a result of ischemia if the blood supply disruption is severe and prolonged. Infarction specifically denotes tissue death caused by ischemia due to a complete blockage of blood flow in a particular area, usually resulting in irreversible damage. Stasis refers to the slowing or stoppage of blood circulation, which can contribute to ischemia but does not directly define the loss of blood supply itself. Therefore, ischemia is the most accurate term to describe the reduced blood flow to tissue.
