Definition
20:1
Term
Which organ controls H2CO3 (carbonic acid) concentration?
Definition
lungs
Term
Which organ controls bicarbonate concentrations?
Definition
kidneys
Term
What two values are measured in arterial blood gases and are used to calculate bicarbonate?
Definition
pH and pCO2
Term
Which organ responds faster when pH is altered from normal?
Definition
the lungs
Term
When bicarbonate is decreased, what happens to pH, and what is this called?
Definition
pH decreases; metabolic acidosis
Term
When bicarbonate is increased, what happens to pH, and what is this called?
Definition
pH is increased; metabolic alkalosis
Term
Which is more likely to be corrected by the lungs- acidosis or alkalosis?
Definition
acidosis
Term
When pCO2 is increased, what happens to pH, and what is this called?
Definition
pH is decreased; respiratory acidosis
Term
When pCO2 is decreased, what happens to pH, and what is this called?
Definition
pH increases; respiratory alkalosis
Term
What is the compensation for respiratory acidosis?
Definition
bicarbonate increased by increasing reabsorption
Term
What is the compensation for respiratory alkalosis?
Definition
bicarbonate decreased by decreasing reabsorption
Term
what is the compensation for metabolic alkalosis?
Definition
decreased reabsorption of bicarbonate
Term
what is the compensation for metabolic acidosis?
Definition
decreasing pCO2 by hyperventilation
