therefore , the passive na and cl influx and the cytoplasmic ca flowed in from extracellular spaces and released from secretory granules , an intracellular calcium store , by secretory stimulation probably triggers the passive or active na and cl extrusion and consequently the osmotic water flux from the basal part of acinar cells to the secretory granules and the lumen , as well as the serial exocytosis of the granules in the luminal side of the acinar cells .
