What is frostbite?

Frostbite is accurately described as an injury to the body caused by tissue freezing. This condition occurs when skin and other tissues freeze due to prolonged exposure to extremely cold temperatures, particularly affecting areas such as the fingers, toes, ears, and nose. Frostbite can lead to physical damage and even loss of limbs if not treated promptly, as the blood flow to the affected area is significantly reduced, causing tissues to become damaged.

The other choices provided do not describe frostbite. A type of burn from heat exposure refers to thermal burns, which are injuries caused by heat sources, not cold. An injury caused by electrocution pertains to electrical shock injuries, which affect the body but are unrelated to frostbite. Lastly, internal bleeding from an injury concerns damage to blood vessels and organs that results in blood escaping from the circulatory system, which is also distinct from the freezing of tissues associated with frostbite.
