Question

Pancreatic duct of a healthy dog is blocked. Which of the following function of pancreas will not be affected?

• A. Maintenance of normal blood sugar level
• B. Carbohydrate digestion
• C. Protein digestion
• D. Neutralization of chyme

Answer 1

The correct option is A Maintenance of normal blood sugar level

The pancreas serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland.
Pancreas functioning as an endocrine gland, releases glucagon and insulin into the blood. These hormones are not released through duct. There will be no effect in the functions of glucagon and insulin and so maintenance of normal blood sugar level will not be affected.
Functioning as an exocrine gland, the pancreas secretes enzymes into the small intestine through the pancreatic duct and the ampull of vater. These enzymes break down the proteins, lipids, carbohydrates, and nucleic acids in food.
Sodium bicarbonate present in pancreatic juice neutralizes the acidity of the chyme to prevent damage to the walls of the duodenum and provides a neutral pH environment for the digestion of chyme.
