Answer:
Physical excercise places greater demands on the abilities of the body to maintain a steady state.. Extra heat generated during excercise must be dissipated or abandoned, oxygen demands increase and more waste products such as sweat are produced. Homeostasis controls bodily temperate in ways such as sweating. The maintenance of homeostatis during excercise is principally the job of the circulatory system and respiratory systems, although skin, kidneys and liver are also very important.
