blood vessel
The blood vessels near the skin enlarge so that the hot blood is nearer the surface of the skin to transfer heat away from the body.
you skin and hands
ya
our environment give disease are the result of a performance of the athlete are have a skin cancer, etc.
i think that the skin keeps them cool and doesnt the dolphins get to hot or to cold
There are receptors in the dermal part of the skin that sends various types of information to the brain; hot, cold, light touch, pressure (deep touch) and pain.
Air can vary in temperature, so it can be cold or hot depending on the environment. Cold air is denser and can feel refreshing, while hot air is lighter and can feel warmer on the skin.
The body has a core temperature of about 98.6F for most people. If you are in a hot environment, or have just taken a nice hot shower/bath, your core body temp is going to be affected. To get rid of the heat, the superficial blood vessels, just under your skin, dilate to release the heat to the skin, sometimes in the form of perspiration with a little help from the eccrine (sweat) glands. When those blood vessels dilate so close to the surface of the skin, it causes the skin to become red, flushed or florrid.

A special feature of Phython's skin is that it sheds easily in Summer so that the Phython doesn't get too hot. Also, another one is that the colour of it is usually to blend in with the environment it was born in.
Sweat ducts are part of the skin- which is an organ. Sweating is controlled by a part of the brain called the hypothalamus, which contains temperature receptors to tell you when you are too hot or cold. The maintenance of a constant body temperature is part of homeostasis, which means 'the maintenance of a constant internal environment', so in other words, keeping everything in your body the same to allow everything to function normally.
