Why do we have two kidneys if we can live with just one?

Why do we have two kidneys if we can live with just one?
Why do we have two kidneys if we can live with just one?

Some organs in our body are symmetrical, such as tonsils, lungs, ovaries, other testicles, writes the Italian magazine focus.it.

In some cases, such as that of the kidneys, one of the two has in a sense the function of a somewhat special spare wheel.

What does this mean?

If both kidneys are healthy, they share the task of cleaning the body.

However, if one goes out of order, the healthy kidney can do all the necessary work on its own.

In the case of the kidney, in fact, the organ left alone after a transplant (for a donation or for an illness) goes into hypertrophy, i.e. it becomes bigger, precisely as a result of the work to which it is subjected.

Despite this, so far it has not been demonstrated that this overwork puts the single kidney under greater "stress" than when both are working.

However, it is clear that only one kidney has a reduced functional reserve, so there is no longer a "spare wheel" available, in case of need.
