Which of the following structures is associated with the liver?

The liver is traditionally associated with various organs and systems in the body, particularly in traditional Chinese medicine (TCM), where each organ has specific emotional and physiological correlations. In TCM, the liver is closely linked to the eyes. This connection stems from the belief that the liver stores blood, which nourishes the eyes. A deficiency in liver blood can lead to vision problems, dryness, or even night blindness. Thus, when assessing overall health, practitioners often evaluate the condition of the eyes as they relate to liver function.

In contrast, while the skin, kidneys, and stomach are undoubtedly important organs, their associations are different in TCM. For instance, the skin is thought to be more closely linked to the lungs, the kidneys are associated with reproductive and urinary functions, and the stomach plays a key role in digestion as part of the spleen systems. Each organ has its unique relationships and manifestations, but in the context of liver associations, the eyes stand out as the correct choice.
