It's the Judical branch, the Executive branch and the Legislative branch!
Let's start off with the legislative branch, the legislative branch is basically all the government things. Let's talk about impeachment as well, impeachment is the process where a president could potentially get fired basically. The senate is a big group of people who make laws and the people in it were also elected by the people and the house of represenatives is basically the same with small changes.
So anyways, lets actually talk about the branches.
You might have been wondering one thing, whos in charge here? The vice president is actually leader of the legislative branch but, with the president, theres a vice president so you may have been wondering (again) is there a vice vice president? Well the answer to that is yes but they aren't called a vice vice president they are caled a "president pro tempore" and they are elected by senators.
*snore* The executive branch is probably the most important branch of all, It has many important things such as the president of the USA and the president has a lot more jobs such as making sure laws are good and if they arent, vetoing the laws sent from other branches the current president of the US is Joe Biden but you probably already knew that. The vice president is also pretty important as they are important in the executive branch like the president is, the vice president can also veto laws and help make treaties with other countries if needed. The current vice president is Kamala Harris. Something else that happens in the executive branch is enforcing laws. Enforcing laws is when a new law is passed and people don't know about it so they educate the public about it or do some other things like just arresting someone and many other things. *snore*
The president's cabinet is like helpers for the president, they help make decisions that are important like if the president should go to war or not or something like that.
