A rare informative post in izismile. I question the accuracy of some of the statements, but it was an interesting read.
The main function of the kidneys is to purify blood from waste products. And to succeed at this, each individual kidney has at least one million and up to 2 million special tiny filters, called nephrons.
We don’t really need 2 kidneys, half of one can do just as good a job as 2.
If a child is born with only one kidney, it will grow to the weight of 2 kidneys combined.
