Throughout medical school and into residency, I have always found the interaction between renin and aldosterone very interesting, especially when learning about pathologies with hypertension that can alter their interactions.

Thankfully, we recently had a wonderful lecture that spelled it all out in a way that made much more sense to me.
I made a table as a quick guide (click to download) to help anyone who still has to look up these conditions each time they are mentioned.
