what is the function of integumentary system to control body temperature high?

• arterioles in the epidermis dilate so that more blood flow to the skin
• produce hormones to reduce the metabolic rate
• sweat glands in the skin produce more sweat and hair erector mucles relax to let the hair lie down
• detect the temperature and send to nerve impulses to the brain

• blood glucose level goes back to normal
• the corrective mechanism brings the low temperature up and back to normal again
• excess glucose turn into glycogen
