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.
