A series of event occurs in the body during the process of sneezing. 
Explanation: 
The cleaning process through which the nasal pathway is cleaned automatically by the body is called as sneezing. 
While sneezing, the chest muscles pack the lungs, which send a burst of air upwards. 
The throat closes tight, which at that point sends the air shooting through the nose at velocities up to 100 mph. 
This process leads to a splash of 2,000 to 5,000 microscopic organisms' filled droplets coming out form the nose and mouth while sneezing.
