What is an example of a sensory organ?

The nose is an example of a sensory organ because it plays a crucial role in the sense of smell, one of the human senses. It is equipped with specialized cells known as olfactory receptors, which detect airborne chemicals and send signals to the brain, allowing the perception of different odors. This capability is essential for various functions, including recognizing food, detecting dangers (like smoke), and contributing to the overall experience of flavor.

In contrast, the other options do not function as sensory organs. The heart is primarily responsible for pumping blood throughout the body, the liver has vital roles in metabolism and detoxification, and the kidneys are key in filtering blood and producing urine. While all these organs are important for maintaining bodily functions, they do not provide sensory input in the way that the nose does.
