The US Senate is composed of two senators from each state. Their terms are six years. The US Constitution provides this guideline.
United States Senate
The Westminster system is a democratic parliamentary system of government modelled after the politics of the United Kingdom. This term comes from the Palace of Westminster, the seat of the Parliament of the United Kingdom.
The system is a series of procedures for operating a legislature. It is used, or was once used, in the national legislatures and subnational legislatures of most Commonwealth and ex-Commonwealth nations upon being granted responsible government, beginning with the first of the Canadian provinces in 1848 and the six Australian colonies between 1855 and 1890. However some former colonies (e.g. Nigeria) have adopted the presidential system as their form of government.
Senate of Barbados
The Senate is the Upper House of the bicameral legislature the Parliament of Barbados. The Senate is accorded legitimacy by Chapter V of the Constitution of Barbados. It is the smaller of both chambers and also includes HM Queen Elizabeth II, Queen of Barbados (represented by the Governor General). The Senate was established in 1964 to replace a prior body known as the Legislative Council. Besides creating and reviewing Barbadian legislation, the Senate generally reviews approved legislation originating from the House of Assembly (Lower House). One main constraint on the Senate is that it cannot author monetary or budget-related bills. Most of the non-political appointees to the Senate have been selected by the Governor General from civil society organisations, labour collectives and public associations in Barbados.
Classes of United States Senators
The Senate (Dutch: Senaat (help·info), French: le Sénat, German: der Senat) is one of the two chambers of the bicameral Federal Parliament of Belgium, the other being the Chamber of Representatives. It is considered to be the "upper house" of the Federal Parliament. It has undergone several reforms in the past, and will soon be further changed as part of the sixth Belgian state reform agreed in 2011. If the reform is passed, it will no longer be directly elected starting with the 2014 elections, but instead composed of members of community and regional parliaments and co-opted members. It will be a chamber of the communities and regions and serve as a platform for discussion and reflection about matters between the different language communities.

Senate of the Philippines
The three classes of United States Senators are made up of 33 or 34 Senate seats each. The purpose of the classes is to determine which Senate seats will be up for election in a given year. The three groups are staggered so that one of them is up for election every two years.
A senator's description as junior or senior senator is not related to his or her class. Rather, a state's senior senator is the one with the greater seniority in the Senate. This is mostly based on length of service.
The Senate of the Philippines (Filipino: Senado ng Pilipinas, also Mataas na Kapulungan ng Pilipinas or "upper chamber") is the upper house of the bicameral legislature of the Philippines, the Congress; the House of Representatives is the lower house. The Senate is composed of 24 senators who are elected at-large with the country as one district under plurality-at-large voting.
Senators serve 6-year terms, with half of the senators elected every three years to ensure that the Senate is maintained as a continuous body, though staggered. When the Senate was restored by the 1987 Constitution, the 24 senators who were elected in 1987 served until 1992. In 1992 the candidates for the Senate obtaining the 12 highest number of votes served until 1998, while the next 12 served until 1995. Thereafter, each senator elected serves the full 6 years.
