Final answer:
If the pancreatic duct was obstructed, you would expect to see elevated blood levels of lipase.
Step-by-step explanation:
If the pancreatic duct was obstructed, you would expect to see elevated blood levels of lipase. Lipase is an enzyme produced by the pancreas and is responsible for breaking down fats in the digestive system. When the pancreatic duct is obstructed, lipase cannot flow into the small intestine, resulting in elevated blood levels.
