U have 2 but u only need 1
at least one
A live, healthy body to function in.
you wouldn't be able to survive as long as you could have with two kidneys.. in other words two kidneys lengthen your life span..
2 but you can survive on 1
To survive an human needs either one functioning kidney, or regular treatment by a dialysis machine.
You need 1 healthy kidney to live
Depends. Probably his hunger or how much he cares about that person. You only need one kidney to survive..
Not really. That's why we have 2 of them: if one fails, we can still survive with the other one. But if both fail.... we need dialysis to filter our blood :(
Gerbils have evolved special kidneys and some other adaptations to survive with very little, if any, water.
Very unlikely because you only have 2 kidneys and 1 pancreas. Humans need both of these to survive. However if one kidney was still working then you could survive.
A week or 2 at the most
Kidneys filter your blood of toxins and foreign, unwanted substances. It's really cool that you only need one to survive. :)nephrons,glomerulus,ureter
All of them.
