Lungs3

• Carcinoid tumors (sometimes called neuroendocrine tumors) usually originate in hormone-producing cells that line the small intestine or other parts of the digestive tract, but they can also occur in the passageways in the lungs (bronchi) and in other organs. (msdmanuals.com)
• It is a passageway for air between the lungs and the external environment (Anne M Gilory 2012). (bestpremiumessays.com)
• When the nerve endings in the throat, windpipe or lungs sense the irritation, a reflex causes air to be forcefully ejected through the passageways. (pampers.ae)

Windpipe1

• For example, an irritation in the windpipe or bronchi sounds deeper and raspier than when it's located in the larynx. (pampers.ae)

Airway1

Vocal2

• The lining of the larynx below the vocal folds consists of ciliated and goblet cells and the mucus traps dust with the cilia moving the trapped particles upwards. (criticalcarepractitioner.co.uk)
• Elastic ligaments within the folds are pulled by muscles of the larynx which can then stretch the vocal folds so that the opening, or glottis, is narrowed. (criticalcarepractitioner.co.uk)

Abnormal1
