Just for fun, let's start at the heart and then run through the entire cardiovascular system and look at the major blood vessels running to the head, limbs, and organs. This will be introductory, so I'm not going to talk about every blood vessel in your body, but you will have a very good idea of the main arteries and veins if you stay all the way to the end.
Good luck with that.
