What is the name of the lower house in the United States' bicameral legislature?

The House of Representatives is the name of the lower house in the bicameral legislature of the United States. This body shares legislative power with the Senate, which is the upper house. The House of Representatives is composed of members who are elected to two-year terms and represent districts based on population sizes from each state, allowing for proportional representation in the legislative process.

This structure allows the House to be more directly responsive to the public, as representatives serve shorter terms and face re-election more frequently than senators, who serve six-year terms. Additionally, the House has exclusive powers such as initiating revenue bills and impeaching federal officials. Understanding the role and function of the House of Representatives is key to grasping how the U.S. government operates and how laws are created.
