The eye and ear are part of which system?

1. The nervous system

2. The integumentary system

3. The respiratory system

4. The reproductive system

The correct answer is: The nervous system

The eye and ear are integral components of the sensory system, which is closely linked to the nervous system. The nervous system is responsible for processing sensory information from the environment, allowing us to see, hear, and interact with the world around us. The eyes function as organs of vision, converting light into signals that are sent to the brain for interpretation. Similarly, the ears are responsible for hearing and balance, converting sound waves into electrical signals that also reach the brain. This relationship highlights the essential role of the nervous system in integrating sensory inputs and facilitating responses. Thus, identifying the eye and ear as part of the nervous system reflects their fundamental functions in sensory perception.
