SummaryAs living things, we are highly sensitive to changes in our environment; this doesn’t only mean changes outside our body, but changes from within also. For the cells in our bodies to function properly a certain temperature and pH has to be maintained. Even a slight change in pH inside our bodies can cause serious repercussions. Most of the fluids in our bodies range in pH from 6 to 8. Our body has buffers that maintain the pH of blood very close to 7.4 and we can not survive for more than a few minutes even the blood pH has changed slightly. Nature, to make sure homeostasis is maintained, has provided certain molecules that act as buffers. Buffers are molecules that absorb or release protons depending if the solution becomes more acidic (absorbs protons) or more basic (releases protons) (Miyazaki 4).
