THE HEAT DISTRIBUTION SYSTEM IN OUR BODY

     One of the vital cargo packets which are conveyed with blood is heat.This heat spreads all body like a central heating transmitting hot water to all building.However, the source of heat in our  body is not a specific place like boiler of central heating unit. Thanks to blood, heat produced by cells spreads body equally .

                                                                         Many changes occur in our body  according to our

actions' tempo during day.For example, when the heat of  the body increases, the central systemaziter  in brain,hipotalamus, provides blood vessels widen and sudor glands come into action. (1)After that,the heat of body decreases immediately.When the loss of heat in the body emerges,the same central systemaziter do entirely a different operation from the previous one so it makes blood vessels tighten and create thrill.(2)Due to these precautions,the heat of the  body increases , again.

          If we did not have the heat distribution system , we would have a lot of problems.For instance, when we run,our legs  would heat exceedingly and the other parts of body would remain cold .This instable system would damage our metabolism greatly, so we can conclude that distribution of heat to body equally is very important.
            Similarly, blood together with the perspiration mechanism set in so as to reduce the  rising heat in the body. Thanks to this, blood vessels under the skin widen and the heat transmitted by blood releases into the air easily, so when we work in a high tempo, our faces go red due to the widening of vessels. As stated above, blood is very important for our body...
