Three patients in an intensive care unit Examined by a doctor one patient has brain damage from of severe stroke another had a heart attack that severely damaged the heart muscles the last patient has a disease that attacks and breakdown connective tissue in the body all three patients have stabilized and will survive but only one will have a full functioning recovery to regeneration which one and why

Of the three types of tissues mentioned in the answers, both brain, and cardiac tissue are unable to divide and repair themselves. The liver however is the only internal organ that is capable of partial regeneration, which means that it is also the only organ that can be donated in part to a recipient. This means that the only patient that could still be functional after regeneration would be the third who has a severely damaged liver from a crushing injury in a car accident.
