Final answer:
The main body of the Constitution lays out the structure and powers of the three governmental branches, the relationship between the federal government and the states, the process for amending the Constitution, and its ratification.
Step-by-step explanation:
The function of the Articles, or main body, of the Constitution is to outline the structure and powers of the three branches of the U.S. government - the Legislative, Executive, and Judicial branches. Article I establishes the Legislative branch and grants it the power to make laws. Article II sets up the Executive branch, led by the President, and Article III establishes the Judicial branch, which interprets the laws. Additionally, Article IV discusses the federalist system and the relationship between the states and the federal government, while the subsequent articles address the process of amending the Constitution, establish the Constitution as the supreme law of the land, and detail the ratification process of the Constitution.
