Major duodenal papilla

found in the 2nd part of the duodenum

28

Accessory pancreatic ducts can sometimes drain into the duodenum via a ___ ___ ___.

A

minor duodenal papilla

29
Q

Each duct connecting to the Ampulla of Vater has its own ___ to prevent backflow of bile / digestive enzymes.

Q

What causes jaundice?

A

Increase in blood levels of bilirubin
