Question 2

What is normal Blood pH?

Answer 2

7.35-7.45

Question 3

Answer 3

The acidity of the blood must be tightly regulated, marked changes will alter the 3D structure of proteins

Question 4

What percentage of acid produced by the body is respiratory acid?

Answer 4

99%

Question 5

What generates a Rapid compensatory effect?

Answer 5

Changes in ventilation can stimulate a RAPID compensatory response to change CO2 elimination and therefore alter pH

Question 6

What causes a slower compensatory response to increase/decrease;s in pH?

Answer 6

Changes in HCO3- and H+ retention/secretion in the kidneys can stimulate a SLOW compensatory response to increase/decrease pH
