प्रश्न
Which is the correct sequence of air passage during inhalation?
विकल्प
Nostrils → larynx → pharynx → trachea → lungs
Nasal passage → trachea → pharynx → larynx → alveoli
larynx → nostrils → pharynx → lungs
Nostrils → pharynx → larynx → trachea → alveoli
उत्तर
Nostrils → pharynx → larynx → trachea → alveoli
Explanation -
Through the nose, air enters the respiratory system, passing through the pharynx, larynx, trachea, and alveoli. Following inhalation, the diaphragm and intercoastal muscles contract, coupled with the thoracic muscles expanding, allowing air to enter the lungs.
