What condition results from an insufficient blood supply to tissues?

The condition that results from an insufficient blood supply to tissues is ischemia. Ischemia occurs when there is a reduction in blood flow to a specific area, which leads to a shortage of oxygen and nutrients that are essential for cellular metabolism and function. This lack of adequate blood supply can result in tissue damage or dysfunction, as the affected cells cannot perform their normal activities, which may lead to further complications if not addressed.

In contrast, shock is a broader medical condition that can result from various causes, including ischemia, where there is inadequate circulation and blood flow to the organs and tissues of the body as a whole, typically due to low blood pressure or volume. Infarction, on the other hand, generally refers to tissue death (necrosis) due to prolonged ischemia, leading to irreversible damage. Hemorrhage involves the loss of blood and can contribute to or cause shock but not directly describe the insufficient blood supply to tissues itself. Thus, ischemia is the most accurate term for a condition specifically characterized by insufficient blood supply to specific tissues.
