A tissue death within an organ caused by blockage of blood flow is called what?

• A. Infraction
• B. Hypostasis
• C. Ketosis
• D. Hyperthermia

Answer: (A)

When tissue dies because its blood supply is blocked, the process is called infarction. A blocked vessel cuts off oxygen and nutrients to the area, and if the blockage persists, cells die and the affected tissue undergoes infarction. This can happen in any organ, with the heart being a classic example (myocardial infarction) and the brain in ischemic strokes. The other terms don’t describe this situation: hypostasis refers to blood pooling or livor mortis, ketosis is the buildup of ketone bodies from fat metabolism, and hyperthermia is an abnormally high body temperature.
