Question

Can an organ system function correctly when one of its organs does not

Answer 1

yes

Explanation: Because if the organ systems needed both to work most people would die because most only have one kidney

Answer 2

I agree JANHIA but again, your explanation doesn’t make sense I understand having one kidney but, in reality I may just have to have two lungs in order to breathe correctly, a matter a fact, there are certain things objects and miracles science has discovered to help one such (with only one working lung) as this to help them breathe with ease
