For my MYP Personal Project I am doing my topic on the circulatory system. Can anybody give me some history about the circulatory system?
 
I think you should focus less on the history and more on the different types. You could go over the different animal phyla, describing who has an open circulatory system, who has closed ones, who doesn't have any and who has water vascular systems instead of a circulatory system. Then you can go to talk about the differences in the closed circulatory systems in chordates, explaining how some have two-chambered hearts and one circuit while others have 3 1/2 chambers and 2 1/2 circuits. You could also explain about xylem and phloem in plants and how this resemble circulatory systems in animals.
 
i don't know if u'd tink i sound offensive or something, but i think there is no "history of circulatory system"......how abt u change the question to "history of blood circulation?"...if u do that there wud be more answers lyk: "William Harvey of England discovered blood circulation by**......". u cud then just find connections of that to ur original topic abt the circulatory system...aryt?

well then, gud luck on ur project! >peace<
