Acid-Base imbalance compensation Flashcards
Blueprint
What type of relationship do pH and hydrogen have?
A. negative
B. positive
C. mutualistic
A. negative
True or false: hydrogen is an acid.
True
True or false: bicarbonate is a base?
True
Why does hydrogen impact pH?
A. the more hydrogen, the higher the pH
B. the more hydrogen, the lower the pH
B. the more hydrogen, the lower the pH
Which systems work to maintain acid-base balance?
- Buffers
- Respiratory
- Renal system
What is a buffer?
A. manages pH through respiratory speed/ altering CO2 excretion
B. Chemicals that combine with an acid or base to change pH
B. Chemicals that combine with an acid or base to change pH
What do buffers do?
Immediate reaction to counteract pH variations until compensation is initiated.
What are the four major buffer mechanisms?
A. phosphate system, hemoglobin system, protein system, bicarbonate-carbonic acid system
B. potassium system, oxygen system, ribosomal system, bicarbonate-carbonic acid system
A. phosphate system, hemoglobin system, protein system, bicarbonate-carbonic acid system
How do potassium and hydrogen balance the pH?
Potassium and hydrogen move interchangeable into and out of the cell
How does potassium move once hydrogen enters the cell for buffering?
Potassium moves out
What does respiratory manage pH?
A. Altering CO2 intake
B. Altering CO2 excretion
B. Altering CO2 excretion
What would faster respirations do the respiratory pH?
A. Excrete more CO2; decrease acidity
B. Excrete less CO2; increase acidity
A. Excrete more CO2; decrease acidity
What would slower respirations do the respiratory pH?
A. Excrete more CO2; decrease acidity
B. Excrete less CO2; increase acidity
B. Excrete less CO2; increase acidity
When the respiratory system works to regulate the pH, how does it respond?
Quickly, but short lived
What is renal regulation?
A. managed pH through respiratory speed
B. Alters the excretion of retention of hydrogen or bicarbonate
B. Alters the excretion of retention of hydrogen or bicarbonate
Why is renal regulation a long term fix?
It permanently removes hydrogen
Which is true of compensation?
A. The body can over compensate
B. The body only overcompensates when respiratory regulation is triggered.
C. The body never over compensates
C. The body never over compensates
Which of the following is true?
A. If the problem causing the pH imbalance originates in the lungs, the kidneys imitate efforts to correct it
B. If the problem causing pH imbalance originates outside the lungs, the kidneys initiate efforts
A. If the problem causing the pH imbalance originates in the lungs, the kidneys imitate efforts to correct it
- Get rid of HCO3 and H+
What happens if the kidneys and lungs can’t compensate to restore normal pH?
Disease
