pH refers to the degree of acidity or alkalinity of your body tissues. Because your blood is flowing throughout your body the pH of your (arterial) blood is the best indicator of the overall pH of your body. It is maintained in the range 7.33-7.45 where 7.0 is neutral (ie notOHW ...

When you measure pH, the value you see is based on ions, specifically hydrogen ions (H+). The amount of H+ determines the acidity or alkalinity; if there are more hydrogen ions present, then your pH will be acidic (0-7) and if there are less H+ relative to hydroxyl groups (OH-)...
