A 45-year-old woman is seen by her primary care physician complaining of intermittent colicky pain in the right upper quadrant (RUQ), staing sholy after eating a meal, and lasting about 30 min. During these episodes, she feels bloated and nauseated. The patient also states that over the past 2 days, her stools have become very light in color, like the color of sand, and her skin has become yellow. What is the anatomical basis for the clinical condition?
