What is the term for the death of tissue caused by a lack of blood supply?

• A. Infarct
• B. Ischemia
• C. Emesis
• D. Edema

Answer: (A)

The correct term for the death of tissue due to a lack of blood supply is "infarct." When blood supply is hindered to a certain area, it deprives the tissue of essential nutrients and oxygen, which ultimately leads to tissue necrosis or death. This process can occur due to various reasons, such as a blockage in blood vessels caused by a clot or other obstructions. As a result, the affected tissue can no longer sustain itself, leading to the formation of an infarct.

In contrast, "ischemia" refers to the condition of reduced blood flow to tissue, which can lead to infarction if prolonged. However, ischemia itself does not specify the tissue death that follows; it is simply the state of insufficient blood supply.

"Emesis" is the medical term for vomiting and has no relation to tissue death or blood supply. "Edema" refers to swelling caused by excess fluid trapped in the body's tissues, which also does not pertain to the death of tissue from blood supply issues. Thus, "infarct" specifically identifies the outcome of tissue death resulting from inadequate blood flow.
