EXAM III

Question 1

Respiratory compensation (What are the lungs doing in order to compensate for this change in pH?)

Answer 1

-Change in respiratory rate (you’ll breathe faster to get more O2, get rid of CO2) which will help stabilize pH of ECF
-Directly affects carbonic acid–bicarbonate buffer system

Question 2

Renal compensation

Answer 2

-Changes in rates of H+ and HCO3- secretion or reabsorption by kidneys, in response to changes in plasma pH
-Kidneys assist lungs by eliminating any CO2 that enters renal tubules during filtration and diffuses into tubular fluid en route to renal pelvis

Question 3

Respiratory acidosis

Answer 3

When your lungs can’t remove all the CO2 that your body produces, so your blood pH is lower (more acidic) than normal

Question 4

Respiratory alkalosis

Answer 4

When hyperventilation prevents your lungs from removing excess CO2, so your blood pH is higher (more basic) than normal

Question 5

Metabolic acidosis

Answer 5

Caused by a build-up of too many acids in the blood

Question 5

Metabolic alkalosis

Answer 5

???
