Flashcards in Renal Acid Base Mechaninsms Inv In Reg Of Hydorgen Ions In Plasma Deck (13):
1

What can acidosis and alkalosis lead to

Acidosis - depression of cns
Alkalosis - over excitability of pNS and later CNS

2

What can hydrogen ions do to enzymes and pottasium levels

Marked influence on enzyme activity
Influence pottasium levels

3

How are hydrogen ions added

Carbonic acid formation
Inorganic acids produced during breakdown of nutrients
Organic acids resulting form metabolism

4

What is the Henderson hasselbach equation

PH = pk + log(a)/(ha)

A= base
Ha = acid

5

What is the most important buffer physiological system

Co2-HCo3 buffer

6

How is carbonic acid formed

Carbon dioxide plus water with the action of carbonic anhydrase forms carbonic acid

7

What is the role of the kidney in control of the plasma concentration of bicarbonate

Variable reabs of filtered bicarbonate
Kidneys can add new bicarbonate to the blood which is imp to treat acidosis

8

What su another buffer

Phosphate

9

The excess amount of hydrogen excreted as hydrogen phosphate can be measured as

Titratable acid

10

Action of ammonia as a tubular buffer

Acid excreted as ammonium
New bicarbonate formed

11

The vast majority of hydrogen ion secretion used for

Bicarbonate reabs to prevent acidosis

12

Excretion of tetra table acid and ammonium

Rudd the body simultaneously of acid load and regen buffer stores

13

What is the ph of blood
