Detailed explanation-1: -Air then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange. The respiratory bronchioles open into the alveolar ducts, alveolar sacs, and alveoli.
Detailed explanation-2: -Your bronchial tubes lead to smaller air passages called bronchi, and then into bronchioles. The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to your blood.
Detailed explanation-3: -The correct sequence is Pharynx → Larynx → Trachea → Bronchioles.
Detailed explanation-4: -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-5: -We inhale oxygen via nostrils which go down our throat via the nasopharynx. From there it enters the trachea (windpipe), which is further divided into bronchial tubes. The bronchial tube is further divided into bronchioles. The bronchioles finally end in a tiny structure known as alveoli.
