Because of he Constitution the three (not four) institutions are considered co-equal branches of the Federal government. Article I of the constitution created the Congress. The Congress is divided into two parts: the House of Representatives, elected for two year terms and based on the census which distributes the 435 members among each state based on the number of people in that state and the Senate, which consists of 100 members, two from each state. Congress ' two houses must pass a bill which then goes to the President for his signature or veto.
Article II is the Executive or Presidential branch. The President is elected for a 4 year term and is limited to two terms. He may sign a bill into law or veto it. It then returns to the Congress which has the option of passing it over the veto, but it needs a 2/3 majority to override the veto.
The third branch is the judicial branch. The highest court is the Supreme Court. The 9 members are appointed for life by the president with the Senate's confirmation.
The Court may decake a law unconstitutional, or th may uphold the law. he lower courts are the District and Appellate courts. Decisions in those courts may be appealed.
The power of each branch may be checked by any other branch.
