pH means “hydrogen potential”.

(The carbon dioxide comes from the lungs during exhalation. Carbonic acid is a weak acid and is therefore in equilibrium with bicarbonate in solution. When sig- nificant amounts of both carbonic acid and bicarbonate are present, a buffer is formed, because they neutralize each other.)

Under normal circumstances, there’s much more bicarbonate present than car- bonic acid (the ratio is about 20:1). Metabolism produces more acids than bases. It produces acids (even in a balanced body), but the alkaline blood is able to neutralize them. Since relatively small amounts of metabolic bases are produced, the carbonic acid concentration in the blood can afford to be lower. Since car- bonic acid isn’t stable in aqueous (water) solutions, some of it decomposes to form carbon dioxide and water.

Phosphate Buffer System

The phosphate buffer system utilizes the phosphate ions that come from calcium phosphate salts (structural components of bones and teeth) to alkalinize the blood. So, if you eat too many acid-forming foods (for your metabolic type) on a regular basis, your body draws upon your calcium phosphate reserves, leading to the degeneration of bones and teeth (which can increase the amount of cal- cium being eliminated through the kidneys, creating kidney stones).

Protein Buffer System

The protein buffer system is a mechanism for controlling the balance of hydrogen ions (molecules that have lost or gained electrons). Intra and extra
