D. the control center of your body.

What are the name of the cells used by the nervous system?

A. Neurons

B. Nervous cells

The correct answer is:

A. Neurons

The correct answer is D. the control center of your body. The nervous system is responsible for controlling and coordinating all the activities of your body. It processes information from your senses, such as touch, taste, and smell, and sends signals to different parts of your body to initiate actions or responses. The nervous system includes the brain, spinal cord, and nerves that extend throughout your body.

To find the correct answer, you can start by eliminating the options that don't accurately describe the nervous system. Option A, "how you digest food," is not correct because digestion is primarily controlled by the digestive system, which includes organs like the stomach and intestines. Option B, "what keeps you from getting sick," is also incorrect because the immune system is responsible for protecting the body against illness and disease. Option C, "the smallest system," is not correct either. While the nervous system is not the largest system in the body, it is not the smallest either.

By process of elimination, we can determine that the correct answer is D, "the control center of your body," as it accurately describes the role and function of the nervous system.
