Question

What is the normal pH of blood and what can abnormal fluctuations in pH do to cells and tissues in the body?

Answer 1

The normal pH level of blood is 7 most of the time. Blood pH may be changed if acids or bases are added to or removed from the blood. Secretion of an acid (e.g. gastric juice, lactic acid) implies that the acid involved (HCl in this case) is removed from the blood
