After you exercise for a while, you may notice that your skin turns red. (A) How is the blood flow in your limb changes as a response to the exercise? When your skin turns red, how has the temperature changed at the skin surface (Tskin)? (B) During exercise, does the total heat generation rate inside your body increase or decrease from that in normal conditions? (C) What is the relationship between the total heat generation rate and the total heat loss from the skin surface to the environment by convection? Neglect sweating and radiation. (D) The total heat loss from the skin surface to the environment is hA(Tskir-Tair). Based on this convection equation and results in (C), how has the skin temperature changed during exercise? Does Tskin increase or decrease from that in normal conditions? Is this consistent with that in (A)?
