ANATOMY

Detailed explanation-1: -The process of taking air into the lungs is known as inspiration or inhalation, and the process of breathing it out is expiration or exhalation. 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-2: -Answer. Answer: atmosphere→ nasal cavity→ pharynx→ glottis→ larynx→ trachea→ bronchus→ bronchi→ bronchioles → alveoli→ alveolar ducts.

Detailed explanation-3: -In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth). It moves through the pharynx, larynx, and trachea into the lungs. Then air is exhaled, flowing back through the same pathway. Changes to the volume and air pressure in the lungs trigger pulmonary ventilation.

Detailed explanation-4: -Ventilation. Pulmonary gas exchange. Gas transport. Peripheral gas exchange. 20-Jul-2020
