The blood goes down to the feet without warming them up and since the body doesn't have to keep the feet warm is conserves heat energy to the main parts of the body e.g organs and as the blood from the blood vessels returns to the hard it gets warmed up, so the body doesn't get cooled down by the cold blood.

Please?



Which exam board are you doing?
