Which term describes tissue death due to prolonged lack of blood supply?

Explanation:
The main idea is that tissue death occurs when blood flow is reduced for too long. When blood supply is insufficient (ischemia) for an extended period, cells can no longer generate the energy they need and membranes fail, leading to irreversible injury and tissue death—this outcome is called necrosis. In many contexts, necrosis is described as infarction when a larger area of tissue is affected. So a phrase that defines tissue death due to prolonged lack of blood supply aligns with necrosis. Coagulation describes clot formation, not tissue death, and blood is just the fluid involved, not an outcome.
