RPG Kidney Island Map- National Kidney Month

I was messing around last night with paper and pencil and had an idea for a map. So I looked up the inside of a kidney, pulled the basic forms and turned it into an RPG map. The first map is my colored map. The second map is a freebie. A black and white map you can color for yourself! The maps are my own creation, whether correct or not I had fun doing it. I call it Kidney Island.

I am going to bring a copy of both maps to my nephrologist appointment and give them to my doctor. They will be a gift for National Kidney Month.
