What are functional systems?

A functional system is like a team of friends who all have special jobs that help you play your favorite game.

Imagine you're playing a game where you build a house with blocks. One friend brings the blocks, another stacks them, and someone else decides where to put each block. Together, they make sure the house gets built, even if they’re doing different things. That’s like how a functional system works: it's made up of parts that each do their own job but work together to achieve something bigger.

In a functional system, every part has its role. For example, in your body, your heart is one part, it pumps blood, and your lungs are another, they help you breathe. They don’t need to talk or plan, but they still work together so you can run, play, or even sleep.

Think of a functional system like a toy kitchen: the oven bakes the cake, the fridge keeps the ice cream cold, and the plates hold everything. Each part does one job, but all of them are needed for your pretend tea party to be perfect!
