The structure of Congress has been around since 1787, when the Constitution was signed. Back then, it was a lot smaller, with only 65 reps in the House and 26 in the Senate. Over time, it's grown and changed, but the basic idea has stayed the same: to represent the people and make laws for the country.
One of the coolest things about Congress is the committee system. It's like a big team effort, where members work together to discuss and vote on bills. There are committees for everything from agriculture to transportation, and even some pretty weird ones, like the Committee on House Administration (yes, that's a real thing!)
But what really makes Congress tick is the relationship between the House and Senate. It's like a big game of tug-of-war, where each side tries to pull the other in their direction. Sometimes they work together, and sometimes they're at each other's throats (just kidding, it's not that intense... or is it?).
