What is the pH range of human blood at which it works? |
|
Answer» An important property of blood is its degree of acidity or alkalinity. The acidity or alkalinity of any solution, including blood, is indicated on the pH scale. The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40. A doctor evaluates a person's acid-base balance by measuring the pH and levels of carbon dioxide (an acid) and bicarbonate (a base) in the blood. Blood acidityincreases when the Level of acidic compounds in the body rises (through increased intake or production, or decreased elimination) Level of basic (alkaline) compounds in the body falls (through decreased intake or production, or increased elimination) Blood alkalinityincreases when the level of acid in the body decreases or when the level of base increases. |
