The dissection of the larynx and trachea allows for internal viewing and studying of 28 different anatomical details. Trachea cartilage and annular ligaments can be seen moulded into the trachea. To help the studying process, the bronchi of the right and left lobes have been brightly coloured to make the distinguishing the bronchopulmonary segments easier.

The larynx and trachea work together as integral parts of the respiratory system to facilitate breathing and protect the airway. Here’s how they function together:


  • Location: The larynx, or voice box, is located in the neck and sits above the trachea.
  • Function: It plays a crucial role in breathing, sound production, and protecting the trachea against food aspiration.
  • Voice Production: The larynx contains the vocal cords, which vibrate to produce sound when air passes through them.
  • Protective Mechanism: The epiglottis, a flap of tissue within the larynx, closes over the trachea during swallowing to prevent food and liquids from entering the airway.


  • Location: The trachea, or windpipe, is a tube that extends from the larynx down to the bronchi, which lead into the lungs.
  • Function: It provides a clear airway for air to enter and exit the lungs.
  • Structure: The trachea is reinforced with C-shaped cartilage rings that keep it open and maintain its structure while allowing flexibility.

Coordination in Respiratory Processes:

Air Passage:

During inhalation, air passes through the nose or mouth, travels down the pharynx, through the larynx, and then into the trachea before reaching the lungs.

During exhalation, air follows the reverse path, moving from the lungs through the trachea and larynx, and then out through the nose or mouth.

Protection and Sound Production:

The larynx protects the trachea by preventing foreign objects, like food and liquids, from entering the airway. The epiglottis covers the trachea during swallowing.

The vocal cords in the larynx allow for sound production. When speaking, the vocal cords close together and vibrate as air passes through them from the lungs, creating sound.

In summary, the larynx and trachea work together to ensure a clear and protected airway for breathing and to facilitate speech production. The larynx guards the entrance to the trachea and produces sound, while the trachea serves as the main passage for air to travel to and from the lungs.
