Acid-base balance — Flashcards

What is the normal average blood HCO3- concentration (mEq/L)?_____

One function of gastrin is to _____ gastric H+ secretion

In a low K+ state, _____ is exchanged for Na+ in the basolateral membrane of cortical collecting tubule, causing alkalosis and 'paradoxical aciduria'

Increased CO2 (respiratory acidosis) causes a(n) _____ in HCO3- by mass action

Gastrin increases H+ secretion directly via binding to _____ receptors on parietal cells

One function of cholecystokinin is to potentiate the effects of secretin on _____ secretion

Does reabsorption of HCO3- result in net secretion of H+? _____

Release of the enzymatic component of pancreatic secretion is primarily stimulated by _____

Release of the aqueous (HCO3-) component of pancreatic secretion is primarily stimulated by _____

The H+ inside the cells of the early PCT (from H2CO3) is _____ by the Na+-H+ exchanger
