The term bicameral (see unicameral) means two chambers or houses. A bicameral legislature distributes legislative power between two separate legislative bodies.
The U.S. Constitution, which outlines the U.S. system of government (see Americanism), established the legislative branch of the federal government in the U.S. as a bicameral legislature. There are two houses, or chambers, that make up the legislative branch. The U.S. House of Representatives is one of the chambers, or houses, in the legislature and the U.S. Senate is the other chamber. Together, both chambers, or houses, make up the legislative branch of government which is known as the U.S. Congress.
