Help with Triggers in Storyline 360

Hi, I have a slide with a diagram that I would like to make "clickable"- I would like the  learner to be able to click on each circled word to see the definition. I'm able to do that but cannot figure out how to bring the learner back to the original diagram to click a new circle after reading the previous definition. I would like the learner to be able to click whatever circle she/he wants in whatever order and be brought back to the main diagram to click a new circle (or move to the next slide) after reading the definition. 

I am so new to this...can anyone help me figure out how to do this? I've attached the slides I'm working with. 

Thank you!!
