7) One kidney
Humans are normally born with two kidneys but there are some cases in which they are born with only one, which is called renal agenesis (ÒLiving With One KidneyÓ). If a person is born with just one then the other kidney will undergo a regenerative/compensatory growth phase. The cells in the kidney will
proliferate to bring the kidney up to a size that will be more beneficial then stop dividing. We can also have a kidney removed due to disease or a donation
(ÒLiving With One KidneyÓ). There are multiple diseases that attack the kidney leaving it too damaged to repair itself so it has to be removed. Healthy people can also donate one of their kidneys to someone who needs it to survive. So overall even if we only have one kidney we have the opportunity to live normal, healthy lives.
