Category:Heart

The heart is the central organ of blood circulation. It is a hollow muscular organ about the size of a fist, resembling a rounded cone with the tip pointing downwards and to the left, slightly offset to the left side of the body behind the sternum. Only in the relatively rare case of right-heart disease is it more offset to the right side of the body, usually with an overall mirror-inverted organ arrangement (situs inversus). In the macrocosm, the heart corresponds to the Sun and, as a planetary metal, to gold.
