What components make up the central nervous system (CNS)?

The heart and lungs
The brain and kidneys
The brain and spinal cord
The brain and blood vessels

The correct answer is: The brain and spinal cord

The central nervous system (CNS) is comprised of the brain and the spinal cord. This system is crucial for processing information and coordinating bodily functions. The brain acts as the control center, integrating sensory information, regulating responses, and facilitating higher cognitive functions such as thought and memory. The spinal cord serves as the primary conduit for transmitting signals between the brain and the rest of the body, enabling reflex actions and facilitating communication between various body parts. The other options do not accurately represent the components of the CNS. The heart and lungs are part of the cardiovascular and respiratory systems, respectively, while the kidneys are part of the urinary system. Blood vessels transport blood and do not constitute a part of the CNS. Understanding these distinctions is essential for grasping the organization and functions of the human body.
