What are the three branches of the united states government that were established by the u. s. constitution. after identifying each branch explain who makes up that branch and what is their responsibility when it comes to laws.

The three branches of government are:

1. Legislative Branch- it's made of two houses of Congress (The Senate and the House of Representatives. Its responsibility is to make the laws. 
2. Executive Branch- the President of the U.S. is the head of the executive branch. Its responsibility is to enforce the laws. 
3. Judicial Branch- it's made of the court system (The Supreme Court). Its responsibility is to interpret the Constitution and limit the powers of the other branches of government. 

Hope I helped!
