Which of the following is INCORRECT about the pancreas?
Options:
Answer:
Solution:
The pancreas is a composite or heterocrine gland, meaning it functions as both an exocrine and an endocrine gland.
The exocrine portion of the pancreas secretes an alkaline pancreatic juice containing enzymes and bicarbonate ions. The alkaline nature (pH around to ) is essential to neutralize the acidic chyme entering the duodenum from the stomach and to provide an optimal pH for the action of pancreatic enzymes.
The endocrine portion consists of the Islets of Langerhans, which secrete hormones such as insulin and glucagon.
The hepato-pancreatic duct, which carries both bile and pancreatic juice into the duodenum, is guarded by the sphincter of Oddi.
Therefore, the statement that the exocrine part secretes acidic pancreatic juice is incorrect.
Answer: Exocrine part of the pancreas secretes acidic pancreatic juice.
