What describes the gradual warming of frozen tissue?

• A. Rewarming
• B. Active Cooling
• C. Hypothermia
• D. Fever

Answer: (A)

Rewarming is the gradual warming of frozen tissue. When tissue freezes, ice crystals form and damage cells; warming the tissue slowly and in a controlled way helps restore blood flow and metabolic activity without causing additional injury from sudden temperature changes. In practice, this is often done with careful warming, such as warm water immersion around body temperature, to thaw ice crystals while protecting the tissue. Rapid or uneven warming can worsen damage, so the goal is a steady, gradual increase in temperature. The other terms describe cooling (active cooling), a high body temperature from infection (fever), or an abnormally low body temperature (hypothermia), none of which capture the idea of warming frozen tissue.
