What does this hose do?

Have a nice day friends. Photo representation. I have just bought the vehicle. While I was putting in the squeegee, it caught my attention, one of the two hoses in the place I marked in red has nothing attached at the end. What does this hose do? I don't understand engine at all =) thanks
