Answer 2

Human air passageway:

The correct sequence of air passage during inhalation is (d) nostrils → pharynx → larynx → trachea → alveoli.

Explanation:

• The air enters nasal cavity through nostrils and the air filters through mucous membrane.
• The pharynx opens into two tubes which is common for both food (leads to throat) and air (leads to esophagus).
• The larynx is the voice box which helps is formation of the sound. This part prevents the liquids and foods from entering.
• Trachea is a wind pipe is strengthened by rings of cartilage which prevents the trachea from collapsing. It is a 12 cm pipe.
• The alveoli helps in exchange of gases (carbon dioxide and oxygen) between the blood and the lungs.
