Part 3 Flashcards
What in the proximal tubule cells enables ammonia secretion as well as the generation and absorption of bicarbonate?
Ammoniagenesis
Where are high NH4 concentration maintained in?
Medullary intersituim
Where are ammonium ions excreted?
CD
What species has a low basal urinary ammonia excretion rate and does not increase ammonia secretion during metabolic acidosis?
Rabbits
What is when there is an excessive accumulation of CO2?
Respiratory acidosis
What is when there is an excessive elimination of CO2?
Respiratory alkalosis
What is when there is an excessive accumulation of fixed acids or elimination of buffer bases?
Metabolic acidosis
What is when there is an excessive elimination of fixed acids or accumulation of buffer bases?
Metabolic alkalosis
What type of respiratory problem have these causes?
-respiratory pump injury
-severe respiratory disease that obstructs airways or excessively stiffens the lungs
Acidosis
What type of respiratory problem have these causes?
increased PCO2 and H
decreased pH
Acidosis
What type of respiratory problem is treated by restoring alveolar ventilation?
Acidosis
What type of respiratory problem have these causes?
Stim of chemoreceptors by hypoxemia
Stim of intrapulmonary receptors by lung injury
Overly use of a ventilator
Alkalosis
What type of respiratory problem have these causes?
Decreased PCO2 and H
Increased pH
Alkalosis
What type of respiratory problem is treated by the stop of alveolar hyperventilation?
Alkalosis
Acidosis = _____ventilation
