Lung

The lung (from Indo-European: *lengu̯h "light"; Latin: pulmo, -onis m.) is a paired organ used for respiration in humans and almost all air-breathing vertebrates, but also in some fish such as lungfish. It is formed during embryonic development as an outpouching of the foregut. In the macrocosm it corresponds to the planet Mercury and the planetary metal mercury.
