And it's the asinr cells of the pancreas which are responsible for forming this Chimetrypcinogen, as well as other digestive zymogens. And all these Xiaomogens are essentially stored in membrane bound organelles, in membrane bound granules shown in green. And so all these granules that contain the zymogens basically accumulate on the apex side of these asinr cells. And when the cell is stimulated by some type of hormone or some type of action potential, these granules basically exit the cell via exocytosis and they release all these zymogens into the duct. And then the duct basically empties out into a larger duct which eventually empties out into the pancreatic duct. And it's the pancreatic duct that connects directly to the initial portion of the small intestine we call the duodenum.
