What exactly does this part do?
As the title says, I am interested in knowing how this part actually works. Part nr: A272 016 01 34. I have attached two pictures, one of which inside the part. This particular part was taken off a M272 engine.
Also, how does a part like this break or becomes bad? It looks like some of the plastics inside my old part has been broken off. Thanks for any answers.

Correct, it's the oil baffle for your PCV system, kinda like a mini oil catch can.

I imagine it deteriorates with age.

You should more completely identify your vehicles, such as year, and identify the car you are referring to.
