What is mean by homeostasis?

• Controls and coordinates body activities through chemical 
• controls and coordinates body activities through electrical impulses
• For maintenance of a steady state in the internal environment
• remove metabolic waste products from the cel

How blood osmotic pressure will regulate in our body?

• regulate the glucose level in the body
• regulate the amount of water and concentration of salt in the blood

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

which of this activity not involved in negative feedback?

• osmotic pressure decrease and return to normal
• 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
