The exocrine pancreas is one of two compartments that include digestive-acting acinar cells and duct cells.They represent an extension of the intercalated duct into each pancreatic acinus. [1] These cells are commonly known as duct cells, and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin. They also secrete ...
