Vedclass · Answer

(B) $1$. The nose contains fine hairs (cilia) and mucus that act as a filtration system to trap dust, pollen, and other impurities present in the air.$2$. The nasal passage also warms and humidifies the inhaled air before it reaches the lungs.$3$. Breathing through the mouth bypasses these protective mechanisms, allowing unfiltered air containing dust, pathogens, and pollutants to enter the respiratory tract directly, which can lead to infections, irritation, or respiratory issues.
