it has been shown that ( 1 ) resistance measurements have enabled us to demonstrate that during acid secretion there is a neutral mechanism ( s ) for the movement of hco3- out of and the entrance of cl- into the oxyntic cells , ( 2 ) the transmucosal resistance varies inversely with the rate of acid secretion , and ( 3 ) the low resistance of the secreting frog fundus is due to the low resistance of the lumen-tubular cell pathway -- the parallel pathways ( the tic or paracellular and surface cell pathways ) have high resistances .
