The exocrine portion of the pancreas is composed of pancreatic lobules and pancreatic acini. Pancreatic lobules are the structural units of the exocrine pancreas, while pancreatic acini are the functional units responsible for producing and releasing digestive enzymes. The other options, such as pancreatic crypts, triads, and islets of Langerhans, are not part of the exocrine portion of the pancreas. Pancreatic crypts are found in the small intestine, triads are structures found in the liver, and islets of Langerhans are responsible for producing hormones such as insulin and glucagon.
