PHPH If the H + ions are high in number: If the H + ions are high in number: – pH is low – Acidic If the H + ions are low in number: If the H + ions are low in number: – pH is high – Alkaline pH Scale pH Scale – Range from 0-14 0= Acidic 0= Acidic 14= Alkaline 14= Alkaline Normal body range= 7.35-7.45 Normal body range= 7.35-7.45

PHPH Acids are formed as end products of protein, carbohydrate, and fat metabolism To maintain the body’s normal pH (7.35-7.45) the H + must be neutralized or excreted Major organs involved in the regulation of acid and base balance: – Bones – Lungs – Kidneys
