How does blood stabilize the body temperature? - Ans:✔✔-The body stabilizes body temperature by

absorbing heat generated by active skeletal muscles & redistributing it to other tissues. If body temp. is

too high, heat will be lost across the surface of skin. If body temp. is too low, warm blood is directed to

the brain & other temperature-sensitive organs.


Why is maintenance of body pH crucial to body function? - Ans:✔✔-The maintenance of body pH is

crucial to body function because diffusion between interstitial fluids & blood eliminates local deficiencies

or excesses of ions (calcium or phosphate). It also absorbs & neutralizes metabolic acids generated by

active tissues.
