Sneezing is the discharge of autonomous semi air
that happens through the nose and the mouth. When human sneezing, the discharge
of the air can reach speeds of 70 m/s (250 km/h) which the air exit so hard and
fast.
The reasons why sneezing happens to the human are
influenza or the cold temperature, but not only that, because of allergic can
make someone sneezing too. Sneezing can spread the disease through
infected water grains that are between 0.5 and 5 μm in diameter. Approximately
40,000 such water grains can be produced in a single sneeze. Sneezing is an adjustment reaction because it excludes
snot that contains foreign particles or disturbances and cleans the nasal
cavities. When sneezing, the upper of the mouth ("palate") is soft
and the uvula is slim while the back of the tongue rises to close part of the
route to the mouth so that air removed from the lungs can be removed through
the nose. It is possible that the air exits through the mouth, if the sneezing
or the pressure is strong and the mouth can holding on.
This is how sneezing
is happened to the human and it is the natural phenomenon to the human.
