Final answer:
The structure that is not a landmark of the right and left lobes of the liver is d. LPV, which refers to the left portal vein and does not represent a surface landmark of the liver. Other options given are indeed anatomical landmarks associated with the liver's lobes.
Step-by-step explanation:
The correct answer is d. LPV. The liver is a vitally important organ that plays a plethora of roles in metabolism, digestion, and regulation of bodily functions. It is divided into two primary lobes, the right and the left, each filled with functional units called lobules. The liver's landmarks include structures such as the main lobar fissure, gallbladder fossa (GB fossa), and inferior vena cava fossa (IVC fossa), which are associated with its anatomy.
The term 'LPV' usually refers to the left portal vein, which is a branch of the portal vein and not a surface landmark of the liver itself. Hence, the left portal vein is not considered a landmark of the right and left lobes of the liver, making it the correct choice for this question.
