Departments (Spanish: departamentos) form the second level of administrative division (below the provinces), and are subdivided in municipalities.
Except in La Rioja, Mendoza, and San Juan Provinces, departments have no executive authorities or assemblies of their own.
However, they serve as territorial constituencies for the election of members of the legislative bodies of most provinces.
In Tucumán Province, on the other hand, where legislators are elected by zone (Capital, East, West) the departments serve only as districts for the organization of certain civil agencies, such as the police or the health system.
There are 377 departments in all, not including the two "nominal" departments composed of internationally disputed territory in Tierra del Fuego Province: Antártida Argentina, and Islas del Atlántico Sur (which includes the Falkland Islands and South Georgia and the South Sandwich Islands).
