No heartbeat or breathing is called?

• A. Brain death
• B. Functional age
• C. Whole-brain death
• D. Functional death

Answer: (D)

The main idea is the cessation of the body's essential life-supporting functions. When the heart stops beating and breathing ceases, the person is considered to be in functional (clinical) death. This is the point at which the body no longer sustains circulation or respiration on its own, and it is the practical moment many clinicians use to define death. Brain death, by contrast, requires irreversible loss of all brain activity, which can occur even if the heart still beats with support. The other terms don’t fit because functional age isn’t about dying, and brain-related terms describe loss of brain function rather than the immediate stop of heart and breath.
