 * how does the body manage this?**

The body has many tools to keep the body temperature regulated. The integumentary system made up of multiple layers of opithelial tissues that guard muscles and organs. Two of the main jobs of the integumentary system are insulation and temperature regulation. Skin is part of the integumentary system and is made up of the Epidermis (waterproofing and prevents infection), and the Dermis.

the outermost layer of our skin it is the protective layer of skin that covers the body the dermis is the "underlying connective tissue" has no blood vessels and is "nourished by diffusion from the dermis" has many different layers where cells are formed by mitosis (the inner layers) has 25-30 layers of dead skin
 * Epidermis**

the layer of skin underneath the epidermis made up of connective tissue cusions the body from stress and strain has man nerve endings that provide the sense of touch and heat has: hair follicles sweat glands sebaceous glands apocrine glands lymphatic glands blood vessels
 * dermis** http://en.wikipedia.org/wiki/Image:Gray942.png

sweat glands are all over the bodies surface used for temperature regulation coiled tubular glands coming from the epidermis and go all the way into the dermis the hypothalamus senses the core temeprature and also has input from temperature receptors from the skin and is able to controll the sweat output sweat is made up of mostly water and various salts and organic compounds http://en.wikipedia.org/wiki/Image:Gray940.png
 * sweat glands**

the hair follicles lay flat on the skin so that the heat does not get trapped- caused by pili muscles which relax the follicles so that they do not stand up

blood capollaries under the skins surface enlarge so that more heat can be carried and is lost in the air (vasodilation)

__Circulatory System/ Cardiovascular System__**
 * information found off of wikipedia.org

The Circulatory system also known as the cardiovascular system is in charge of maintaining the volume and pH of the blood. The blood evenly distributes heat from the muscles to the rest of the body. This blood transports oxygen and nutrients to the muscles. - The Cardiovascular System also controls the pace of the heart beat pumping fresh blood to the muscles so that they can work at peak efficiency. - Blood - Red Blood Cells carry oxygen and carbon dioxide to muscles. - White Blood Cells fight bacteria and infection - Platelets help blood clot when skin is broken. - Plasma is the liquid substance around cells that helps to transport it effectively through the body - Blood Vessels - Veins: carry blood back to the heart to be replenished with oxygen and nutrients. - Arteries: carry blood away from the heart to the muscles. - Capillaries: Connecting factor between arteries and veins letting blood exchange gases such as oxygen and carbon dioxide - Heart - The heart pumps at a pace to keep blood fresh and circulating to all muscles however hard they may be working.
