andrew11 [14]

Answer:

The answer is True

Explanation:

The Ph of bady fluids have different ranges but it should be nearly constant to maintain the health of the human, The PH of the human blood is from 7.35 to 7.45 and the other blood fluids have different ranges . The PH shouldn't drop below 6.9 because it is so dangerous for human health and result coma. if there is high value of PH this indicates high numbers of OH- and low value of PH this indicates high numbers of H+

each organ has a certain PH value to do its function very well ,there is an organ needs acidic environment to work well and other organ needs an alkaline environment to do its work.
