MEDICAL PHYSIOLOGY

Detailed explanation-1: -Convection. Convective heat loss is the transfer of heat from a body to moving molecules such as air or liquid. The thin air layer adjacent to the skin is heated by conduction from the body but carries the heat away from the body in the ambient air currents.

Detailed explanation-2: -Convection. Convection is heat loss via rapid movement of air or water around us. For example, wind can make us cooler because it’s blowing away the warm layer of air immediately surrounding us and replacing it with a new layer, which we heat and which is in turn blown away to start the process again.

Detailed explanation-3: -Convection occurs when heat is carried away from your body via moving air. If the surrounding air is cooler than your skin, the air will absorb your heat and rise. As the warmed air rises around you, cooler air moves in to take its place and absorb more of your warmth.

Detailed explanation-4: -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.
