What is a primary function of the kidney?

they do a lot more than I thought they did I'm very impressed

this was easy

my extra fluid removal is fine

My Uncle had his kidney removed when he was 14. The scar is still visible and he is 79 come September. His daughter has 3 kidneys should he ever need one.

Thanks meryl

little b, Do you have one kidney or two?

I have a kidney❤
