Why is a person declared dead when their heart stops functioning even though their brain is still functioning?
As soon as the heart stops it's game over for your brain. You have less than a minute till the brain will shut down due to the lack of oxygen. Similarly you can be declared brain dead but still have your heart beating.
Like I said, as soon as you 'flatline' it's essentially game over. Obviously attempts of revival can succeed in cases but you only have a short window after the 'time of death' i.e the 'flatline' to do so.
There was one case (off the top of my head) where someone went around 3 hours I think it was before they were able to restart her heart. That was only due to the conditions in which the body was preserved in the accident (she was skiing and the body was cooled and slowed down enough in the ice for her to be able to have the brilliant medical staff bring her back hours later).

Why do doctors consider a person dead when the brain is not working but the heart is still beating?

Why people are declared dead when the brain stops functioning even when the heart is still beating?

Despite the heart continuing to beat, without brain function, the body cannot sustain life.

If you are brain dead do your kidney still functioning?
Yes, if a person is declared brain dead, their kidneys can still function for a time, as brain death means the loss of all brain activity but does not immediately halt other organ functions. The kidneys can continue to filter blood and produce urine, but they may eventually fail without brain signals that regulate bodily functions. In some cases, kidney function can be maintained temporarily through medical interventions. However, without brain activity and support, overall organ function is likely to decline over time.
