Which is the order of airflow during inhalation?
tigry1 [53]

Answer:

Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.

Explanation:

The air travels through the respiratory system during inhalation in the next order:

  1. <em><u>Nasal cavity:</u></em> You inhale air into your nose.
  2. <u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
  3. <u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
  4. <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
  5. <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
  6. <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
