Explanation:

• Pons: Involved in sleep, respiration, etc., but not the main control for heart rate, BP.
• Cerebrum: Responsible for higher - order functions (thinking, memory), not vital life - support centers.
• Midbrain: Involved in vision, hearing, motor control, not vital centers for heart rate, etc.
• Medulla oblongata: Contains vital centers that regulate heart rate, respiration, blood pressure.
