Unit 2, L21 Acid Base 3

Question 1

Metabolic acid-base disorders

Answer 1

Disturbances of acid-base balance results from a change in bicarb concentration of ECF

Question 2

Respiratory acid-base disorders

Answer 2

Disturbances of acid base resulting from a change in PCO2

Question 3

What is the 3 pronged defense to defend against changes in body fluid pH produced by acid-base disturbances?

Answer 3

Extracellular and intracellular buffering
Adjustments in blood PCO2 via alterations in the ventilatory rate of the lungs
Adjustments in RNAE

Question 4

What is the principal ECF buffer

Answer 4

Bicarb buffer system

Question 5

What happens to bicarb when a nonvolatile acid is added to body fluids

Answer 5

Bicarb is consumed during the process of neutralizing the acid load and the concentration of bicarb of ECF is reduced

Question 6

What happens to bicarb when a nonvolatile alkali is added to body fluids

Answer 6

H is consumed, causing more bicarb to be produced from the dissociation of H2CO3, so bicarb concentration increaes
