Sneezing is a reflex action that occurs when a substance irritates the respiratory passages. An involuntary sneeze is initiated either to remove or dislodge the particular substance.
During respiration it is the nose or nasal cavity that filters the air using mucous and hair within the nose, warms the air and moistens. This is performed when inhaling.
Upper respiratory means your lungs and the breathing passages in your chest area. If you gasped or breathed while vomitting you might get some of the vomit in your lungs. Vomit that passes through your nose might infect your sinus area.
