I came across this PDF file of a textbook. I’m not sure exactly which textbook this has been taken from, so please excuse me from not being able to properly credit those concerned with the publishing of the book.
I found this useful and suggest that you should take a look at it. The topic consists of the two houses of Parliament and their roles. Do go through these few pages! 🙂
