How do buffers play a role in
homeostasis in living things?

In biological systems, chemical buffers prevent sharp and sudden changes in pH.

In biology, homeostasis refers to stable conditions required for the survival of organisms.The pH is a scale used to determine how acidic/basic water is. The pH range from 0 to 14 ( a pH equal to 7 is neutral).In human blood normal pH is about 7.35 to 7.45. A sudden change in this value alters and negatively affects the homeostasis of the body.The carbonic acid-bicarbonate is the most important chemical buffer which is used for mantaining acid-base balance (homeostasis) in the blood.The blood pH can change due to respiratory acidosis/alkalosis and metabolic acidosis/alkalosis.

In conclusion, chemical buffers prevent sharp and sudden changes in pH.
