What are the different systems of the human body?

-And what are their functions? Please help me ASAP. I need to pass my homework about the different systems of the human body and their function/s tomorrow. Please HELP ME!
Update: Thank you very much, Lady Lorne! I'm copying what you wrote. But my teacher told me that there are 11 systems. But I'll just research about the other one left. But thanks anway!
