The U.S. government is divided into three branches: the legislative, executive and judicial branches. There are several divisions within each branch that operate in conjunction with one another to establish a balance between the three branches.
The legislative branch is primarily made up of Congress, which is divided into two chambers: the Senate and House of Representatives. By law, there are 435 representatives that proportionally represent the population of the 50 states. The purpose of the House of Representatives is to create and pass laws on a federal level. The House is also responsible for the impeachment of federal officials and the election of the president in case of an electoral tie.
The main body of executive branch is comprised of the president of the United States, the vice president, the executive office of the president and the cabinet. The president operates as head of state and commander-in-chief. His duties are to implement and enforce laws passed by Congress. The vice president must be ready to assume presidency in the event that the president is unable to perform his duties.
The judicial branch is primarily made up of the U.S. Supreme Court and the U.S. Court of Appeals, which includes criminal and civil courts. The courts help settle disputes between the legislative and executive branch and interpret the law to ensure it is being implemented properly. Members of the judicial branch are appointed by the president and authorized by the Senate.
