Underneath the stomach 1 of 19 What is special about the pancreas? It performs both endocrine and exocrine functions 2 of 19 What do most cells within the pancreas do? Manufacture and release digestive enzymes 3 of 19 What type of function do most of the cells in the pancreas perform? Exocrine Function 4 of 19 How are the cells arranged? They are arranged around tiny tubules where they excrete digestive enzymes into. 5 of 19 How is the pancreatic duct formed? Tiny tubules joining together 6 of 19 What does the pancreatic duct do? It collects fluid containing digestive enzymes and carries it to the first part of the small intestine 7 of 19 What three enzymes does the pancreatic fluid contain? Amylase, Trypsinogen, Lipase 8 of 19 What is amylase? A carbohydrase 9 of 19 What is trypsinogen? Inactive protease 10 of 19 What else does the pancreatic fluid contain and why? Sodium hydrogencarbonate to neutralise the digestive contents that has just left the acidic stomach 11 of 19 What areas of the pancreas secrete hormones? Islets of Langerhans 12 of 19 What two types of cell do the Islets of Langerhans contain? Alpha cells and Beta cells 13 of 19 What do the alpha cells do? Manufacture and secrete glucagon 14 of 19 What do beta cells do? Manufacture and secrete insulin 15 of 19 What type of function do the Islets of Langerhans perform? Endocrine fucntion 16 of 19 Why are the Islets of Langerhans well supplied with blood capillaries? To allow the hormones to be secreted directly into the blood. 17 of 19 What does glucagon do? Causes blood glucose levels to rise 18 of 19 What does insulin do? Causes blood glucose levels to fall. 19 of 19
