MEDICAL PHYSIOLOGY

Detailed explanation-1: -The body loses 65% of its heat through radiation. Conduction (such as heat loss from sleeping on the cold ground). Heat is lost in air temperatures lower than 20°C (68°F). The body loses about 2% of its heat through air conduction.

Detailed explanation-2: -Topic Overview. The body loses heat through: Evaporation of water from your skin if it is wet (sweating). If your clothing is wet, you will also lose some body heat through evaporation and through respiration (breathing) when the body temperature is higher than 37°C (99°F).

Detailed explanation-3: -Heat loss occurs primarily from the skin of a patient to the environment through several processes, including radiation, conduction and convection, and evaporation. Of these, radiation is most significant and accounts for ∼60% of total heat loss.

Detailed explanation-4: -In hot conditions Eccrine sweat glands under the skin secrete sweat (a fluid containing mostly water with some dissolved ions), which travels up the sweat duct, through the sweat pore and onto the surface of the skin. This causes heat loss via evaporative cooling; however, a lot of essential water is lost.

Detailed explanation-5: -Answer and Explanation: The primary source of body heat is nutrient oxidation. We are endothermic organisms, meaning that we can regulate and maintain our body temperature at a stable level. This means that we constantly need to be burning fuel to maintain this internal temperature.
