Centroacinar cells are present in ?

Ans. is 'a' i.e., Pancreas Pancreas It is a mixed exocrine and endocrine gland. A . Exocrine pa The exocrine poion is a compound acinar gland, consists of pancreatic acini. The acini of pancreas consist of a group of pyramid-shaped acinar cells' (pancreatic parenchymal cells) arranged around a small lumen. The centroacinar-cells are seen at the centre of acini where the duct system begins. These cells are an extension of the intercalated duct cells into the acinus. They add bicarbonate ions to pancreatic juce. Individual acini are drained by intercalated ducts (interalobular ducts), which drain into larger interlobular ducts, found in connective tissue septa. B. Endocrine pa Islets of Langerhans constitute the endocrine pa and are scattered throughout the exocrine pa, most abundandly in tail region.
