Question

A) More air containing the odor is brought into contact with the olfactory epithelium.
B) Impulses originate slowly in the olfactory epithelium.
C) The tissue needs more time in contact with the odor.
D) Threshold for odor detection is high.

Accepted Answer

Inhaling deeply and slowly through the nose allows for more air containing the odor to come into contact with the olfactory epithelium, which contains the receptors for detecting different odors. This increases the likelihood of identifying the odor.
