Why would sniffing rather than inhaling normally tend to increase the stimulation of olfactory receptor cells?

The first is that it increases our ability to smell, enhancing the detection of odorous molecules in the air. The second is a peripheral drive in the brain to synchronize rhythmic activity, which is the concurrent firing of neurons in the olfactory bulb with breathing.

Why can I taste when I exhale?

It sounds counterintuitive, but it’s exhaling that pushes molecules of food from the back of your mouth up to your nasal passage. This is called your “retronasal” sense of smell, and it plays a key part in giving us a full experience of a food’s flavor.

A one-inch square area on foot of nasal cavity on each side of nasal septum, receptors cells surrounded by supporting cells. How and why does sniffing increase your ability to detect an odor?

Should you exhale before swallowing?

In adult humans, swallowing usually starts during the expiratory phase of breathing, and respiration resumes with continued expiration after swallowing.
