1.	Give scientific reason :Pancreas is both exocrine as well as endocrine gland.
Answer» 1. Pancreas is heterocrine gland i.e. both exocrine and endocrine gland. 2. The exocrine part is pancreatic acini. The cells of acini secrete pancreatic juice containing digestive enzymes like trypsinogen, chymotrypsinogen, etc. 3. Endocrine part of pancreas is made up of groups of cells called Islets of Langerhans. There are four kinds of cells in islets of Langerhans which secrete hormones. Alpha (α) cells (20%) secrete glucagon. Beta (β)) cells (70%) secrete insulin. Delta (δ) cell (5%) secrete somatostatin. PP cells or F cells (5%) secrete pancreatic polypeptide (PP). Hence, pancreas is said to be exocrine as well as endocrine gland.
