Final answer:
Pancreatic digestive secretions are collected in the Duct of Wirsung, also known as the pancreatic duct, where they are then transported to the duodenum to aid digestion. The acinar cells produce the enzyme-rich pancreatic juice, while the Islets of Langerhans are involved in the hormonal functions of the pancreas.
Step-by-step explanation:
The student has asked where pancreatic digestive secretions are collected. Pancreatic juice, an enzyme-rich fluid necessary for digestion, is produced by clusters of cells known as acinus or acinar cells, which are part of the pancreas's exocrine system. These secretions are collected in the Duct of Wirsung, also simply known as the pancreatic duct. From here, the pancreatic juice is transported to the duodenum where it aids in the digestion process.
It is worth noting that while acinar cells produce and secrete the pancreatic juice, the Islets of Langerhans play a crucial role in the endocrine function of the pancreas, producing hormones like insulin and glucagon.
The Common bile duct is not where pancreatic secretions are collected, but rather, it merges with the pancreatic duct just before releasing bile into the duodenum via the hepatopancreatic ampulla. So, the correct answer to the student's question is option B, the Duct of Wirsung.
