Verified step by step guidance1
Understand that the sense of smell, or olfaction, involves detecting chemical substances in the air.
Recognize that when you smell something, it is because tiny particles of that substance are released into the air.
These particles are then inhaled through the nose, where they come into contact with the olfactory receptors located in the nasal cavity.
The olfactory receptors detect these particles and send signals to the brain, which interprets them as specific smells.
Therefore, the aspect of the substance that enters your nose to create the sensation of smell is the particles of the substance itself.
