Transcript text: What structure connects the larynx to the primary bronchi?
Multiple Choice
Bronchioles
Pharynx
Esophagus
Trachea
Alveolar ducts
Solution
The answer is the fourth one: Trachea.
Explanation for each option:
Bronchioles: These are smaller air passages in the lungs that branch off from the bronchi, not the structure that connects the larynx to the primary bronchi.
Pharynx: This is a part of the throat situated behind the mouth and nasal cavity, and above the esophagus and larynx. It is not the structure that connects the larynx to the primary bronchi.
Esophagus: This is a muscular tube that connects the throat (pharynx) with the stomach. It is part of the digestive system, not the respiratory system.
Trachea: This is the correct answer. The trachea, also known as the windpipe, is the tube that connects the larynx to the primary bronchi, allowing air to pass to and from the lungs.
Alveolar ducts: These are part of the respiratory system located within the lungs, leading to the alveoli where gas exchange occurs. They do not connect the larynx to the primary bronchi.
In summary, the trachea is the structure that connects the larynx to the primary bronchi.
