Which term refers to a condition marked by cell death due to lack of blood supply?

The condition characterized by cell death resulting from a lack of blood supply is known as an infarct. An infarct refers specifically to the area of tissue that undergoes necrosis (cell death) due to the cessation of blood flow, which can occur as a result of an obstruction, such as a blood clot. This lack of blood supply deprives the affected cells of oxygen and nutrients, leading to cell death.

While ischemia refers to the reduced blood flow to tissues, it does not necessarily result in cell death unless prolonged or severe enough to cause necrosis. Necrosis itself describes the broader process of cell death that can occur due to various reasons, including infarcts or other damage. Pathology, on the other hand, is the study of diseases and does not specifically relate to the process of cell death due to a lack of blood supply.

Thus, the term 'infarct' is the most accurate choice in this context, as it precisely describes the condition of localized cell death resulting from an interruption of the blood supply.
