The nasal canal is made up of olfactory cells that allow you to detect odors.
When particles dissolve in the air and you detect smells, it is called olfaction. Olfaction is the sense of smell, where specialized receptor cells in the nasal cavity are activated by airborne molecules, allowing you to perceive different scents.
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
The olfactory cleft is located at the rear of the nose. It consists of two narrow chambers through which air flows.
Choanocyte (collar cells) are any of the flagellated cells located in the body cavity of a sponge. They surround the base of the flagellum. The function of these cells is to maintain the flow of water through the body of the sponge.

The olfactory epithelium, located in the upper part of the nasal cavity, holds the olfactory receptor cells responsible for detecting smells. It contains specialized nerve cells that send signals to the brain when they detect specific odor molecules.
The cone-shaped cells in the eyes detect colours.
