Justify why blood has a very narrow normal pH range. What happens if the blood pH gets too high or too low?
What will be an ideal response?
Homeostasis requires that the pH of body fluids be maintained almost constant to avoid disruptions of normal cell and tissue function. If the pH of the blood and body fluids gets too high, alkalosis occurs, causing uncontrollable muscle contractions. If the pH of the blood and body fluids gets too low, acidosis occurs and will result in coma and death.
