The molecules from the food are being aerosolized and diffuse for the area of higher concentration around the food to fill the rest of the room

The molecules attach to a bipolar nueron located in the nose. This causes ions channels to open within your cells. And action potential is sent to the first order nueron. This nueron carried the information to your medulla. In your medula the message is sent up a second order nueron to the olfactory cortex of your postcentral gyrus, where the information is interperted.

As the smell of food enter your nasal passage, it gets converted to a electrical signal and your olfactory gets activated. Your parasympathetic system is now activated and gets your digestive system prepared for food. Your parasympathetic system initiates secretion of digestive enzymes and movements: saliva (in your oral cavity), peristaltic movements (in your esophagus), activation of the lower and upper sphincters, and secretion of pepsin and HCl (in your stomach). When no food actually comes down your esophagus into your stomach, you get those lovely, embarrassing stomach growls.
