2nd Lesson With The Doctor Flashcards
What is the name of the enzyme that speed up the conversion of bicarbonate to water and carbon dioxide and vice versa
Carbon anhydrase
Where is the carbon anhydrase
Alveoli
Renal tubes
What is the most powerful buffer in the extracellular fluids
It is the bicarbonate
The most important buffer in the renal tubes and in extracellular
It is the phosphate buffer
What happens when the CO2 concentration increases
The number of bicarbonate increases which means the number of the H+ increases and the Ph lower
If the pt getting only 1/4 (25%) alveolar ventilation how mush is his pH decreased
It is decreased by 0.45
If the ph reach 7 how how is the alveolar react
They increase their rate by 5-6 times and bring it up again in 3-12min
Is the ventilation rate reacts equally to the increase and decrease of the pH
No it responda more in the low pH than high pH .
Because when we have high pH the ventilation decrease and as a side effect the O2 level decrease which will stimuli the alveolar to increase the ventilation
What is the nonvolatile acids
The acids that can’t be excreted by lungs because they are not bicarbonate
