a: Circulatory system ~
b: a radiator to dissipate heat
What: "The body's normal temperature is around 37C, but it can rise in summer, during exercise or when we are ill. Our body regulates this via evaporation, in the form of sweat, to cool us down. "Our circulatory system is like a radiator to dissipate heat," says Dr Dominic Micklewright, a sport and performance expert at the British Association of Sports and Exercise Sciences. Sweat is mostly water, but also contains sodium, chloride, potassium, calcium and other minerals. "
