Explanation:

The major organ involved in heat loss is the skin which is responsible for approximately 90% of heat loss. Skin is the largest organ in the human body. Thermoreceptors in the skin consist of free nerve endings with sensory axons that transmit information to the spinal cord. Different types of cation channels activate within nerves depending on the temperature.
