Question

We sweat more when we do hard physical work. Also we breathe at a faster rate. why? (HINT : metabolic reactions)

Answer 1

Answer:

When you exercise or any physical work you need energy.

When you need energy you generate energy.

When you generate energy you need metabolism.

Metabolism needs oxygen.

Lungs breath faster to draw in oxygen, which helps cells make energy in the mitochondria.

Heart rate increases to keep up with the demand of blood which circulated throughout the body to transfer energy, oxygen, and nutrients to the regions that need it.

Heat is created as the body works. Work generates energy which heats the body.
