#8 Acid Base Balance Flashcards
The pH of the ECF is tightly controlled between what pH?
how much H+ does a person generate every day?
1meq/kg per day
T/F The concentration of H+ in the body fluids is low?
what pH is compatible with life?
what is the major buffer in the body?
what is the function of carbonic anhydrase?
converts co2 and H20 into H2CO3
what is the henderson hasselbalch equation?
acid base: pH=6.1 + log [HCO3-]/[.03CO2]
changes in the pH as a result of HCO3- are termed?
metabolic acid base disorders
changes in the pH as a result of CO2 are termed?
respiratory acid base disorders
what primarily regulates HCO3?
what primarily regulates the co2?
carbohydrates and fats in the presence of insulin and O2 result in what?
CO2 and H2O
what does it mean to be a volatile acid?
an acid derived from hydration of CO2. (Gases)
sulfuric acid, hydrochloric acid are examples of what?
non volatile acids
what forms when you combine KCO3 with sulfuric acid?
you form a salt
why do you want to form sodium salts?
because in this form you can excrete them in the kidneys
The net of the diet results in volatile/non volatile acid production?
about how much H+ do we excrete in our urine per day?
70mmol/day (40 from NH4+ and 30 from titratable acids)
How do you secrete acids?
majority is in the kidneys as a salt (titratable acids) and as ammonium
what is the net urinary excretion equation?
acid excretion = titratable acids (bound to H+) +(NH4+) - HCO3
how much HCO3 is reabsorbed per day?
