I need to write a 5 paragraph essay (approximately 2 pages long) and I got to pick the subject i wanted. I chose to write about how blood is transferred through the heart and where it goes throughout the body. I would like to add a diagram but i don't think i'm allowed to do so. I also feel like that isn't enough information to fit into 5 paragraphs so what do you suggest i should do in order to broaden the essay up? (only helpful answers please and thank you!)
