Congress of the Philippines is the national legislature of the Philippines. It is a bicameral body consisting of the Senate (upper chamber), and the House of Representatives (lower chamber), although colloquially, the term "Congress" commonly refers to just the latter. The Senate is composed of 24 senators half of which are elected every three years. Each senator, therefore, serves a total of six years. The senators are elected by the whole electorate and do not represent any geographical district.
