3. The kidneys

We have two kidneys, and both of them are organs you can live without. Sure, it is always better to have your kidneys, but in case you no longer have one of them, you need to know that you can still survive. Unfortunately, if you lose both of them, your chances of survival are pretty slim.

These bean-shaped organs play an extremely important role in our bodies. They are responsible for filtering our blood from toxins, and they also produce hormones that regulate our blood pressure.

As we said, since you can live without a kidney, this makes it possible to donate one of them. The National Kidney Foundation states that the only problem with having one kidney is the concern that something might go wrong with it later in life. In this scenario, having a single kidney means that you have zero backup. Still, they are one of the few organs you can live without.

Now, if it ever happens to remain with no kidneys at all, you can still live, but it will be extremely challenging. You will need to go through dialysis. This is a treatment that basically substitutes for the job of the kidneys. It filters the toxins and removes the excess water from your bloodstream. If a person begins this process, they will need to undergo it indefinitely until they get a kidney transplant.
