what is the function of integumentary system (skin & connective tissue) 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
