Red blood cells and body heat
Name: Jeremy D Phillips
What, if anything, do red blood cells have to do with the regulation
of body heat?
Red blood cells have very little to do with temperature regulation, but
blood is very important as a fluid. When you are cold, the body directs blood
flow away from hands and feet so the blood doesn't get cooled off out there.
When you are hot, blood is sent preferentially to the skin, especially face, so
heat can be dissipated. That is why you turn red when you are hot.
