Terms to Know
Acid-Base Balance

The amounts of acids and bases in the extracellular fluids of the body; amounts of acids vs. bases affects the overall pH of extracellular fluids.

Acids

Substances that increase the amount of hydrogen ions (H+) in a liquid and lower the pH.

Bases

Substances that decrease the amount of hydrogen ions (H+) in a liquid and raise the pH.

pH

A measure of whether a liquid has a lot of hydrogen ions (H+) or relatively few hydrogen ions. The lower the pH, the more hydrogen ions it has, and the more acidic it is. The higher the pH, the fewer hydrogen ions it has, and the more basic it is.
