Humans are endotherms and this means we are warm blooded we keep our body operating at thirty seven degrees Celsius regardless of the external conditions however this is a real challenge as our environment changes all the time depending on the weather, our clothes, if we are inside by the fire or outside having a snowball fight. So how does this work? It's quite similar to the heating system in a house. in a house is a thermostat that measures the temperature if the house gets cold the thermostat will tell the radiators to turn on and heat it up if it's too hot they will be told to switch off simple. Your body works in just the same way here in your brain as a special area called the hypothalamus and it measures the temperature of the blood flowing through it and also it collects information from temperatures senses around the body. it then decides if the temperature is too hot or too cold and we'll try and bring it back to thirty seven degrees Celsius. If you are too hot the hypothalamus can then send signals out to the body by the nervous system that can cause barriers to fact. It can send a signal to your skin and cool sweat glands to secrete the sweat on to the surface of the skin the sweat itself is not cold but it works because it takes the heat away from your body in order to evaporate it. Another way of losing is vasodilation let kind of these blood vessels narrows this. That said the skin open white and allow blood to flow through them. They heat is radiated from the blood into the air and the blood cools down. If you get too cold you can do the opposite with these blood vessels and place them on keeping the blood away from the surface of the skin this is called vasoconstriction this is when your muscles contract in order to make. Another fact you may have noticed when you are cold against them. If you look more place the at least the Bulls what you realized is that each of the little bugger has a has to hit out at. These has stood up on and struck a layer of air around the skin air is a fantastic insulate of heat and this will keep you nice and warm.\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv
