Hello wikipedia! I think this article will benefit from a few new sections: hemodynamics (explore relationships with preload, cardiac output, and perhaps demonstrate principles with pressure volume curve(s)); regulation of afterload. I added the regulation section and will find good sources soon. I also think work can be done on clinical relevance/pathology section , especially in terms of citations. Thanks much!
