What condition can result from a lowering of body temperature leading to tissue freezing?

The condition that results from a lowering of body temperature leading to tissue freezing is best described as frostbite. Frostbite occurs when skin and other tissues freeze due to exposure to very cold temperatures, which can damage the tissues in localized areas, most commonly the fingers, toes, nose, and ears. This happens when the temperature drops significantly, and the blood flow to the affected area is reduced, causing ice crystals to form in the cells.

Cold illness is a broader term that encompasses various conditions related to cold exposure, including both hypothermia and frostbite. However, it does not specifically refer to the freezing of tissues, which is characteristic of frostbite. Therefore, frostbite is the most accurate and specific answer to the condition described in the question.
