Potassium is one of the major electrolytes (together with sodium, chloride and magnesium) that conducts electricity in the human body. It also plays important roles in muscle contraction, nerve impulse transmission, and in maintaining the balance of fluids in the body.
The first modern usage of the specific term social justice is typically attributed to Catholic thinkers from the 1840s, including the Jesuit Luigi Taparelli in CiviltÃ  Cattolica, based on the work of St. Thomas Aquinas.
The term society came from the Latin word societas, which in turn was derived from the noun socius (comrade, friend, ally; adjectival form socialis) used to describe a bond or interaction between parties that are friendly, or at least civil.
