The fact that the government is divided into three branches is known as the "division of power" - the power is distributed to avoid power abuse, so that no instance has unlimited power.
The fact that the three branches are overlapping is known as "checks and balances" - the branches check the other ones (whether their function is lawful) and balance each other.
The framers of the constitution understood that free speech/expression were imperative rights for citizens to have. This is based on their experience as colonists under British control. When ruled by the British, American colonists were forced to pay taxes that they never voted on or approved.
This sparked outrage among some American citizens, causing them to express their concerns in a public manner. This ability to share their views was the cornerstone of America's ability to declare independence from Great Britain. The framers wanted to make sure that once the colonists had their own country that they would have this right to freedom of expression.
