Answer 11

On the left side of the median plane.

Question 12

Where is the body of the stomach located, relative to the median plane?

Answer 12

Along the median plane.

Question 13

Where is the pylorus of the stomach located relative to the median plane?

Answer 13

On the right side of the median plane.
