Branches of the U.S. Government: Structure, Powers & Functions
The United States government operates on a strong system of separation of powers to prevent the concentration of authority in any single institution. This framework, designed by the framers of the U.S. Constitution, divides the government into three branches—Legislative, Executive, and Judicial. Each branch has specific roles and checks on the others, creating a balanced democratic system.
1. Legislative Branch
“The Law-Making Branch”
The Legislative Branch is responsible for making laws. It functions through the U.S. Congress, which is a bicameral (two-chamber) institution:

3. Judicial Branch
“The Law-Interpreting Branch”
The Judicial Branch interprets laws and ensures they align with the U.S. Constitution. It resolves disputes and protects fundamental rights.
A. The Supreme Court
-
Highest court in the U.S.

B. Lower Federal Courts

Checks and Balances: Preventing Abuse of Power
Each branch can limit the powers of the others. Examples:
-
President can veto laws passed by Congress.
-
Congress can override a veto with a two-thirds majority.
-
Supreme Court can strike down unconstitutional laws.
-
President appoints judges, but Senate approves them.
This system ensures accountability and protects democratic values.
