The heart is often referred to as the "king" of the body in various contexts. This analogy highlights its crucial role in maintaining life by pumping blood throughout the body, delivering oxygen and nutrients to every cell.
The heart's importance is underscored by its historical and cultural significance. For example, Harvey described the heart as the "king" or "sun" of the body, emphasizing its cosmological significance.
Furthermore, the heart's role as a sophisticated information encoding and processing center further strengthens its claim as the "king of organs."
In Traditional Chinese Medicine (TCM), the heart is also considered the "king of organs," as it plays a critical role in maintaining overall health and well-being.
