Wisconsin CNA State Exam Vocabulary Practice

Which parts make up the central nervous system?

1. Heart and lungs

2. Liver and kidneys

3. Stomach and intestines

4. Brain and spinal cord

The correct answer is: Brain and spinal cord

The central nervous system is made up of the brain and spinal cord, not the heart and lungs, liver and kidneys, or stomach and intestines. The central nervous system is responsible for controlling the body's actions and transmitting signals to and from the brain to the rest of the body. While the heart and lungs, liver and kidneys, and stomach and intestines are all important organs, they are not part of the central nervous system. They are part of different organ systems that work together to keep the body functioning properly. Therefore, options A, B, and C are incorrect because they do not make up the central nervous system.
