Everything about Acid-base Homeostasis totally explained
Acid-base homeostasis is the part of
human homeostasis concerning the proper balance between
acids and
bases, in other words the
pH. The body is very sensitive to its pH level. Outside the range of pH that's compatible with life,
proteins are denatured and digested,
enzymes lose their ability to function, and the body is unable to sustain itself.
Mechanism
The
kidneys maintain acid-base homeostasis by regulating the pH of the
blood plasma. Gains and losses of acid and base must be balanced. The study of the acid-base reactions in the body is
acid base physiology.
Buffering agents
Any substance that can reversibly bind hydrogen ions is called a
buffering agent. They function to impede any change in pH. Hydrogen ions are buffered by extracellular (for example,
bicarbonate,
ammonia) and intracellular
buffering agents (including
proteins and
phosphate).
