Q

What are the three pH regulatory systems of the body?

A

Lungs-remove CO2
Kidneys- remove H+,retain HCO3
Buffering-resist pH change

Q

What does pH actually tell you?

A

the ratio between conjugate base/acid in the blood and thus how much H+ is present

Q

does buffering remove H+ ions?

A

no it mere “absorbs them”

17
Q

What kind of acid can the lungs deal with?

A

only volatile acid (carbonic acid)

18
Q

What is the primary buffering molecule in the Extracellular fluid (ECF)?

A

Bicarbonate

19
Q

What is the primary buffering molecule in the intracellular fluid (ICF) and tubules of the kidney?

A

Phosphate

20
Q

Why is phosphate used in the ICF instead of Bicarbonate?

A

because the pH intracellularly is near the pKa of the phosphate buffer system so it is at peak efficiency

21
Q

If a patient has a pH of less than 7.4 and an HCO3- concentration of less than 24mM/L they have what acid base disorder?

A

Metabolic Acidemia

22
Q

If a patient has a pH of more than 7.4 and an HCO3- concentration greater than 24mM/L they have what acid base disorder?

A

Metabolic Alkalemia

23
Q

If a patient has a pH of less than 7.4 and an PCO2 concentration greater than 40mmHg they have what acid base disorder?

A

Respiratory Acidemia

24
Q

If a patient has a pH of more than 7.4 and an PCO2 concentration less than 40mmHg they have what acid base disorder?

A

Respiratory Alkalemia
