Best way to learn how the US healthcare system works?

Canadian here, so I know quite a bit about how our healthcare system works. But what is the best way to learn how the American health system works? I'd love to learn more about this considering I'd like to attend school and eventually practice in the USA. Wikipedia seems pretty good, but any other recommendation? I find most sources tend to politicize it (in both directions) and I'm looking for a more objective point of view. Thanks!
