I was watching some How I met your mother clip and was kinda wondering what "kidneys" had to do with this guy's origin story.
So anyways, apparently "riñón" also applies to the backside area. That's so weird to me. Is this the most common meaning, or is it usually taken to mean the organ?
As for why I recognized the organ, it's because I know "renal" refers to the kidney, and awhile ago I took an anatomy class in Spanish… only a few random things I remember though
