Final answer:
The ears, nose, and eyes are part of the sensory system, not the integumentary system, which consists of skin, hair, and nails.
Step-by-step explanation:
The ears, nose, and eyes are in the sensory system. The integumentary system consists of the skin, hair, and nails, but it does not include sensory organs like the ears, nose, and eyes. The integumentary system's main functions are to provide a protective covering for the body, sense the environment, and help the body maintain homeostasis. The sensory system is separate and responsible for processing sensory information that allows us to hear, smell, and see.
