Abstract:
Active secretion of Ca2+ is observed from the serosal to the mucosal surface across adult rat duodenum in vitro when absorptive Ca2+ flux is saturated by a high [Ca2+]. Sodium and chloride are spontaneously secreted by this tissue with Cl secretion apparently accounting for about one-third of the short-circuit current when there is no absorptive co-transport of Na+.
