Answer :

As the respiratory system is a very basic topic, you must include the basic information about each organ and if possible, get reference from internet to get some extra info. They help in letting the teacher know that the student has done research on the topic. There are two options, either get the whole respiratory system on a thermocol or highlight each organ separately. You can ask your teacher that. Do remember to understand the topic nicely so that you might be able to score well in exams too. I am providing you with some photographs too:
