Yesterday afternoon, a 55-year-old female came to the gastroenterologist's office complaining of severe pain in her upper right abdomen. She was nauseated and stated that for several months—and especially following meals—she had been having periodic abdominal pain. After several tests, she was diagnosed as having gallstones and was scheduled for the surgical removal of her gallbladder.

As you read this chapter, consider the following questions:

1. What is the function of the gallbladder?

2. How does the gallbladder empty bile into the small intestine?

3. What conditions can result if gallstones are not removed?

4. Will this patient need to change her diet once her gallbladder is removed?
