Hepato-pancreatic duct opens into the duodenum and carries (a) bile                                                                  (b) pancreatic juice (c) both bile and pancreatic juice                              (d) saliva

Answer:

 (c) The duct of gall bladder along with hepatic duct from the liver forms the common bile duct. The bile duct and the pancreatic duct open together into the duodenum as a common hepato-pancreatic duct which carries both bile and pancreatic juice. Bile is secreted by the hepatic cells of liver and is stored further in a thin muscular sac called gall bladder. Secretion of pancreatic juices takes place through the exocrine part of pancreas which consist of round lobules called acini. Saliva is mainly produced by the salivary glands.
