Heart and Soul are both "Sil?"

I'm trying to make some runes using dovazul as part of a project. Problem I'm running into is that I need a translation for both Heart (as in the organ) and soul. Unfortunately it seems they both translate to "Sil" despite the fact that the site's dictionary on the word doesn't even mention the word "heart." I'm guessing this is because the word "heart" was only considered as synonym to "soul," but I need a translation for the organ itself. Is there a better word I could use?
