The four mechanisms of heat loss are:
- Evaporation - When heat is used to convert the water in sweat to water vapour it helps cool the body down
- Radiation - exposed parts of the body radiate heat away from the body
- Conduction - clothes and other objects in contact with the body take the heat up
- Convection - when air passes over exposed parts of the body it is heated and rises upwards. It is then replaced with cool air (causing convection currents)

What is an adiabatic process?
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
The loss of body heat by conduction can be enhanced by?
Convection
What is adiabatic proccess?
An adiabatic process is a process that takes place without any loss or gain of heat.
What what is the heat escape lessening position help designed to prevent?
The loss of body heat when in the water
The process by which the body regulates between heat and heat produced in known as?
Thermoregulation
Im trying to do my anatomy paper and one question states which of the following is NOT a process for heat loss from the body a-oxidation b- conduction c-radiation and d-evaporation?
Oxidation. That is a chemical reaction process that has nothing to do with heat loss.
What is the heat escape lessening position h.e.l.p designed to prevent?
The loss of body heat when in the water
What is the significance of uncoupling proteins in adipose tissue?
increased loss of body heat
What is an adiabatic process?
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
Heat is eliminated during the process of freezing this loss of heat is considered what kind of change?
This loss of heat is considered a physical change.
What is the fastest method of body heat loss?
In high temperatures there are several methods of body heat loss. One is metabolic heat loss, which is where the metabolism of the body produces heat which is increased in higher temperatures, this in turn produces heat loss. There is heat exchange which is where body heat is lost when making contact with a cooler object. Also conductive heat exchange allows the body to lose heat as coming cool, like water or air, move around the person. The body also uses radiant heat exchange which is where the blood is sent to the superficial arteries and veins to let off heat. Finally there is evaporative heat loss which is of course when a person sweats and as that sweat evaporates it takes body heat with it, thus in turn cooling the body down.
What is the balance between the heat loss and the heat produced by the body?
the right side
What is the heat escape lessening designed to prevent?

The loss of body heat by conduction can be enhanced by?
Convection
