Explanation:
Detailed explanation-1: -Blood rich in carbon dioxide travels to the heart, which pumps it to the lungs. Carbon dioxide goes from the capillaries around the alveoli into the alveoli. Then carbon dioxide goes up the bronchioles to the bronchi, and then to the trachea to be exhaled.
Detailed explanation-2: -Air is inhaled through the mouth or the nose. The sequence of air passage during inhalation is as follows: Nostrils→pharynx→larynx→trachea→alveoli.
Detailed explanation-3: -Answer. Answer: atmosphere→ nasal cavity→ pharynx→ glottis→ larynx→ trachea→ bronchus→ bronchi→ bronchioles → alveoli→ alveolar ducts.
