What happens to the respitatory system when you sneeze?

When you sneeze, the respiratory system initiates a rapid expulsion of air from the lungs through the nose and mouth. This process begins with a deep inhalation, followed by the closure of the vocal cords and a buildup of pressure in the chest. The sudden release of pressure causes a forceful blast of air, which can expel irritants, allergens, or pathogens from the nasal passages, helping to clear the airways. This reflex action is a protective mechanism to maintain respiratory health.
