Human blood is normally ........

Explanation:

Human blood stays in a very narrow pH range around (7.35 - 7.45). Below or above this range means symptoms and disease. If blood pH moves to much below 6.8 or above 7.8, cells stop functioning and the patient dies. The ideal pH for blood is 7.4
On the other hand the pH of saliva is usually between 6.5 - 7.5. After we chew and swallow food it then enters the upper portion of the stomach which has a pH between 4.0 - 6.5.
