Final answer:
Frostbite is the condition where body parts turn blue and blotchy due to exposure to cold temperatures, resulting from the freezing of skin and underlying tissues.
Step-by-step explanation:
When a part of the body turns blue and blotchy after being exposed to cold temperatures for a long period, the condition is known as frostbite. Frostbite occurs when the skin and the tissue just beneath it freezes. The body responds to cold by constricting blood vessels in the skin to minimize heat loss, which in severe cases can lead to frostbite, especially in extremities like fingers and toes. This condition can result in tissue damage that may be permanent and, in extreme cases, could necessitate amputation.
Instances of frostbite are different from conditions like hypothermia, which refers to a drop in the body's core temperature, and sweating, which is the body's way to cool down during hot conditions. The best immediate response to frostbite is to slowly warm the affected areas, but medical attention is often necessary for severe cases.The local cooling of the body, when exposed for a long period of time, causing a part of the body to turn blue and blotchy is called frostbite. Frostbite is a condition that occurs when the skin and underlying tissues freeze due to extreme cold temperatures. It can result in permanent tissue damage and may require amputation of the affected area.
