She has a history of multiple similar episodes over the past year. An ultrasound of the right upper quadrant reveals gallstones. Due to the recurrent nature of her disease, she undergoes an elective laparoscopic cholecystectomy. While in the operating room, the surgeons use the laparoscope to visualize a structure connecting the liver to the anterior wall of the abdominal wall. Which of the following embryologic structures eventually ends up within the visualized structure?
