The Security Council has primary responsibility, under the Charter,for the maintenance of international peace and security. 

The Economic and Social Council  (ECOSOC) is a founding UN Charter body established in 1946. The world’s economic, social and environmental challenges are discussed by the Council, which issues policy recommendations.

The Secretariat — comprising an international staff working in duty stations around the world — carries out the diverse day-to-day work of the Organization. It services the other principal organs of the United Nations and administers the programmes and policies laid down by them.
