Temperature+(Anh)

how does temperature control in our body?





The human body has the remarkable capacity for regulating its core temperature somewhere between 98°F and 100°F when the ambient temperature is between approximately 68°F and 130°F. This presumes a nude body and dry air.  The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalamus. The hypothalamus contains not only the control mechanisms, but also the key temperature sensors. Under control of these mechanisms + The flowing of blood in our body help use to keep warm. +When we feel chill or cold, it stimulates our muscles. +Shivering to increase heat production in the muscles  +in case of hot temperature, our body becomes hot. +Our skin has minute pores and sebaceous glands.  +when our body cannot resist excess heat, it secretes sweat through these pores keeping body cool.
