The question can be answered in a variety of ways. You areencouraged (and in some case required) to use graphs and diagramsas part of your answer, to illustrate your argument or particularconcept. This question requires a discussion of vertebratecardiovascular system other than human.
The vertebrate cardiovascular (CV) system has a job ofdelivering a variety of molecules, entrained in plasma, to all thecells in your body. How does it achieve this function effectively(at sufficient rate) and efficiently (with minimal energetic cost)?How does the transport & transfer function differ in extantendotherms and ectotherms? Among vertebrates there's a wealth ofcirculatory designs, each of which must perform thetransport/transfer function. Human CV system is similar only tothat of other mammals (and birds, to some extent), but why wouldyou leave out other vertebrates? How do their CV systems work? Howgood are they at transport? What are the constraints in differentCV systems? So much to write about... This discussion shouldinvolve different cardiovascular systems.
