Regarding body temperature, what would you have expected to see/ record? Was this the case? your recorded results of two mechanisms that explain the phenomenon of body temperature - which one were they? So how does the body actually use these to maintain constant body temperature?

Answer 1

Since the muscles are doing more work which causes release of heat so one would expect to see rise in the body temperature.

But from the above table there is a slight decrease in the body temperature. So the case is just opposite what is expected. The temperature is actually maintained at about a constant rate (just a slight decrease).

Two mechanisms that would explain this are :-

I) Perspiration level (sweating)

II) Body colour which shows the blood flow to the skin and the other organs (including the periphery) is increased.

These two regulate the body temperature and maintain a constant body temperature by :-

? During exercise the core temperature of the body increases so as a compansation mechanism the body cool itself by perspiration. We sweat a lot during exercise which when gets evaporated lowers down the rising body temperature.

?Also the blood flow to the periphery increases (skin and other parts) which helps to release more heat from the body. So more heat can escape from the body. And thus bring down the temperature.

Thus by this way these two parameters maintain constant body temperature.
