Questions: Which of the following receives air directly from the trachea during inspiration? Pharynx Bronchioles Alveolar ducts Bronchi Larynx

The answer is: Bronchi

Explanation for each option:

• Pharynx: The pharynx is a part of the respiratory system that is located above the trachea. Air passes through the pharynx before reaching the trachea, not after.

• Bronchioles: These are smaller air passages in the lungs that branch off from the bronchi. Air reaches the bronchioles after passing through the bronchi.

• Alveolar ducts: These are tiny ducts that connect the bronchioles to the alveolar sacs in the lungs. Air reaches the alveolar ducts after passing through the bronchioles.

• Bronchi: The bronchi are the main passageways that branch off from the trachea and lead into the lungs. During inspiration, air travels directly from the trachea into the bronchi.

• Larynx: The larynx is located above the trachea and is involved in voice production. Air passes through the larynx before reaching the trachea.

In summary, during inspiration, air travels directly from the trachea into the bronchi.
