The olfactory system.
It is neither, it is an organ. Your nose is made of different tissues performing a similar function. It contains cartilage, mucous membrane, bone, blood vessels, and a sensory organ called the olfactory bulb. So your nose is definitively an organ. An organ system is a bunch of organs, like your heart, liver, lungs, etc. working together to perform a specific task. So your respiratory system contains your nose, trachea, and lungs, all different organs working for the same cause.
The nose is not an organ and is apart of the respiratory system. The eye itself is its own organ.
