A piece of thread was tied tightly around an animal's pancreatic duct. The animal subsequently had difficulty in digesting food but did not get diabetes. Explain.

Answer

When a piece of thread is tied tightly around the animal's pancreactic duct, then the pancreatic duct gets closed due to which pancreatic juice containing digestive enzymes cannot go into small intestine. In the absence of pancreatic juice, the animal has difficulty in digesting food. The pancreas however, releases insulin hormone directly in the blood due to which the animal does not get diabetes
