When you touch something that is colder than your body temperature, the heat from your body will transfer to the colder item. The temperature of your body and the item you touched tries to equalize. The perfect example of this is when you sit on one end of a couch for a while. When you get up and put one hand on the area where you sat and the other hand on an area where you did not sit you will feel difference in warmth between the two places. The hand that is on the place where you sat should feel warmer than the hand where you did not sit. This is also why when you sit on cement or a rock that has been in the shade you will start to feel much cooler.

How can the body lose heat from radiation conduction and convection?
For example, you are touching something that feels like you are putting your hands into something very ice cold. That is how you can lose heat from your body.
Does your body lose heat by conduction while in a swimming pool?
Quite so. The water in a swimming pool is cooler than body temperature (unless the swimming pool is actually a hot tub) and therefore, a person in that pool will lose heat by conduction.
When you get cold while your swimming does your body lose heat from conduction convection radiation or reflction?
"Reflction" (I assume you mean "reflection") isn't really a way to lose heat. Convection is really only important within a body; it's largely irrelevant when talking about heat transfer from one distinct body (you) to another (the water). There may well be convection in the water, but that has only a secondary impact on you and how cold you are.That leaves radiation and conduction. Both of these processes are going on, but of the two, conduction is by far the more significant in this particular case.
What do you call the heat transfer from one body to another?
Heat Conduction.
Heat is transferred from your body into an ice cube by?
conduction

What do you mean by conduction of heat?
the transfer of heat from one end of body to another end of body is called conduction of heat

When a person is overheated why does the skin become flushed and hot?
When the core body temperature rises, the peripheral vasculature dilates, specifically the small arterioles and capillaries under the skin. This is to help lose heat by conduction. You also will sweat, to lose heat by evaporation.
How animals cope with heat?
There are four avenues of heat loss: convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such conditions, the only means by which the body can rid itself of heat is by evaporation. So when the surrounding temperature is higher than the skin temperature.
Describe how the body can loose heat in conduction convection and radiation?
you are swimming in ice cold water and losing heat. How does heat leave your body?
Heat transferred from sand to towel to body is transferred by what?
Heat is transferred from sand to towel to body by conduction because of direct contact.
What is the difference between the transfer of heat by conduction and that by radiation?
In conduction, parts of the object move, taking their heat with them. In radiation, the body transfers heat by electromagnetic radiation - often in the infra-red wavelengths.
