It’s our most forceful spasmodic convulsion, the main purpose of sneezing is precisely to expel irritation from the nasal cavity and airway is exactly why we do it and why effective.
> During a sneeze, we depress our palate while the back of the tongue elevates to partially close the passage to the mouth, creating a venturi (similar to a carburetor aka Bernoulli’s principle) air ejected from the lungs is accelerated through the mouth and thus creating a low pressure point at the back of the nose.
