=== Smell ===
{{main|Olfaction|l1 = Olfaction}}
Smell is the process of absorbing molecules through [[Olfactory system|olfactory organs]], which are absorbed by humans through the [[nose]]. These molecules diffuse through a thick layer of [[mucus]]; come into contact with one of thousands of [[Cilium|cilia]] that are projected from sensory neurons; and are then absorbed into a receptor (one of 347 or so).<ref>{{Cite journal|title=Science is perception: what can our sense of smell tell us about ourselves and the world around us?|journal = Philosophical Transactions.

Smell is also a very interactive sense as scientists have begun to observe that olfaction comes into contact with the other sense in unexpected ways.<ref>{{Cite web|url=https://www.apa.org/monitor/2011/02/scents.aspx|title=Scents and sensibility|last=Weir|first=Kirsten|date=February 2011|website=American Psychological Association|access-date=11 December 2018}}</ref> It is also the most primal of the senses, as it is known to be the first indicator of safety or danger, therefore being the sense that drives the most basic of human survival skills. As such, it can be a catalyst for human behavior on a [[subconscious]] and [[instinct]]ive level.<ref>{{Cite journal|last=Bergland|first=Christopher|date=29 June 2015|title=Psychology Today|url=https://www.psychologytoday.com/us/blog/the-athletes-way/201506/how-does-scent-drive-human-behavior|journal=How Does Scent Drive Human Behavior?}}</ref>
