Nephron's

Hey guys so I just started homeostasis in my grade 12 biology class, and we started working on the function of the kidneys and nephrons and all that fun stuff. My question is because I have a piss poor chemistry background, seeing as I can't remember anything since grade 10 science. So I was wonderi...

Liver and Kidney Evolution! Please Help!
