a. A-Cystic duct, B – Common bile duct, C – Pancreatic duct, D – Hepato-pancreatic duct
b. A – Common bile duct, B – Cystic duct, C – Pancreatic duct, D – Hepato-pancreatic duct
c. A – Cystic Duct, B – Bile duct, C – Hepato-pancreatic duct, D – Pancreatic duct
d. A – Cystic Duct, B – Pancreatic duct, C – Common bile duct, D- Hepato-pancreatic duct

Answer 1

Hint: The gastrointestinal tract consists of a series of hollow organs and tubes that begin from the mouth, through the stomach, small intestines, large intestines, and end at the anus. Different organs secrete a variety of enzymes that aid in digestion as the food particles are gradually digested as they pass through the different compartments of the gastrointestinal tract.

Complete answer:
Three accessory digestive organs are responsible for digestion in the small intestine: the liver, the pancreas, and the gallbladder. The liver's digestive function is to generate bile and export it to the duodenum. In the liver, bile helps to digest and absorb fats, vitamins and cholesterol is made. The gallbladder stores concentrate and release bile. The pancreas produces pancreatic juice and sends it to the duodenum, containing digestive enzymes and bicarbonate ions.

In the gall-bladder, the bile flows into the cystic duct. The cystic joins the common hepatic duct, creating the common bile duct from which the bile flows into the small intestine. Pancreatic juice and bile juice are secreted together into the duodenum via the hepatic duct. Pancreatic juice is also present in the secretion from the hepato-pancreatic duct.

Hence, the correct answer is option (A), A-Cystic duct, B – Common bile duct, C – Pancreatic duct, D – Hepato-pancreatic duct.

Note: The pancreas releases digestive enzymes such as proteases, amylases and lipases. These enzymes assist in the absorption of sugar, proteins and fat. The pancreas secretes hormones such as insulin and glucagon into the blood and the islets of Langerhans are embedded in it, and these hormones are released by beta cells and alpha cells respectively.
