increased bile flow rate at the site of bsp excretion ( canaliculi ) produced by bile salt administration permits an increase in the original t ( m ) to occur without the limiting biliary concentration being exceeded . ( b ) there is excretory competition between bsp and bile salt but over a certain range of bile salt administration the facilitatory effects of increased bile flow rate outweigh the inhibitory effects due to competition . ( c ) since secretin administration had no effect on bsp t ( m ) , it is likely that the hydrocholeresis it produces originates downstream from the canaliculi , i.e . in the bile ductules or ducts ;
