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.
Justice also has implications for the way the larger social, economic, and political institutions of society are organized. Social justice implies that persons have an obligation to be active and productive participants in the life of society and that society has a duty to enable them to participate in this way.
