What is the term for a necrotic area of tissue following cessation of the blood supply?

The term "infarct" refers specifically to a localized area of tissue that undergoes necrosis due to a lack of blood supply. This process typically occurs when a blood vessel is obstructed, leading to insufficient oxygen and nutrients reaching the affected tissue. Consequently, the tissue cannot sustain its metabolic functions and begins to die, resulting in an infarct.

While "necrosis" also describes the death of cells or tissue, it is a broader term encompassing various types of cell death, not limited to situations caused specifically by vascular obstruction. "Lesion" is a general term for any abnormal tissue change or damage, whereas "tumor" refers to an abnormal growth of tissue, which can be benign or malignant. The precision of the term "infarct" to describe this specific type of tissue death caused by interrupted blood flow solidifies its status as the correct answer.
