While a member of the senate is called a senator, a representative is simply called a congressman or a congresswoman. However, collectively, both senators and representatives are also referred to as congressmen. The word Senate comes from the Latin word senate meaning old man.
The United States Senate is a legislative chamber in the bicameral legislature of the United States, and together with the House of Representatives makes up the U.S. Congress. The composition and powers of the Senate are established in Article One of the U.S. Constitution. Each state, regardless of population, is represented by two senators who serve staggered six-year terms. The Senate chamber is located in the north wing of the Capitol, in Washington, D.C. The House of Representatives convenes in the south wing of the same building.
