What term is used to identify when a cell is temporarily deprived of blood supply
Infarction
Ischemia
Necrosis
Inflammation
The Correct Answer is B
Ischemia refers to the temporary deprivation of blood supply to a particular tissue or organ, resulting in reduced oxygen and nutrient delivery to cells. This can lead to cellular injury and, if prolonged, irreversible damage. Infarction, on the other hand, refers to the death of tissue due to prolonged ischemia. Necrosis is a type of cell death that occurs when cells are damaged or injured and cannot survive. Inflammation is the body's response to tissue injury or infection, and can be a result of ischemia or necrosis.
