The olfactory system, responsible for the sense of smell, relies on specialized receptors located primarily in which part of the body?

Explanation

The olfactory system, responsible for the sense of smell, relies on specialized sensory receptors located primarily within the nasal cavity, which detect various airborne chemical molecules and send corresponding signals to the brain for interpretation as specific smells. The sense of smell is closely and significantly linked to the sense of taste, which is part of why food often seems to lose much of its perceived flavor when a person has a stuffy nose during a cold. The human olfactory system is capable of distinguishing an enormous range of different smells, though this ability can vary somewhat between individuals.
