Question

How do the pulse and breathing rates maintain homeostasis

Answer 1

The body needs to maintain the amount of oxygen that reaches our cells. If we exercise a lot, our breathing rate increases. More oxygen enables our cells to   more quickly respire aerobically, so that our muscles can contract more rapidly.

Answer 2

Answer:

   Homeostasis is the maintenance of steady internal conditions by living organism.

   So the pulse rate indicate the pumping cycles of blood in heart per second.

   If the oxygen concentration is lower, or we need more blood in body organs, Pulse rate increase and vice versa.

   So it is the mechanism of maintaining standard oxygen level in blood or in organ.

   Hence it helps in homeostasis.
