Which system consists of the CNS and the Peripheral Nervous System and is controlled by the Cardiac Control Centre?

• A. Nervous System
• B. CNS
• C. Cardiac Control Centre
• D. Movement of blood

Answer: (A)

The nervous system. It includes the brain and spinal cord (the CNS) together with the nerves outside the CNS (the PNS), and the Cardiac Control Centre helps regulate heart rate by sending autonomic signals through these nerves. That regulatory role ties the system to nervous system control. The CNS alone wouldn’t cover peripheral nerves, the Cardiac Control Centre isn’t itself a whole system, and moving blood is a process, not a system.
