Correct sequence of the air passage in humans is
Nose → Larynx → Pharynx → Bronchioles → Alveoli
Nose → Pharynx → Larynx → Bronchioles → Bronchi
Nose → Pharynx → Larynx → Bronchioles → Trachea
External nostril → Nasal passage → Internal nostril → Pharynx → Larynx → Trachea → Bronchi Bronchiole → Alveoli
Trachea is a straight tube extending up to the mid – thoracic cavity, which divides at the level of
fifth thoracic vertebra into right and left bronchi
third lumbar vertebra into right and left bronchi
fifth thoracic vertebra into right and left bronchiole
last thoracic vertebra into right and left bronchi
