pH

Definition: The term pH is used to describe the measurement of acidity or alkalinity of a substance.
  • pH of 7.0: Neutral
  • pH below 7.0: Acid
  • pH above 7.0: Alkaline
The pH of body fluids is regulated, but different parts of the body have different pH ranges. For example, stomach acid has a low pH and blood has a pH that is slightly alkaline.
