Where is the submucosal gland ciliated duct located?
Located in the submucosa of the trachea and primary bronchi, these ducts traverse the mucosa to deliver mucus secretions into the airway lumen.
What is the function of the submucosal gland ciliated duct?
The ciliated duct conducts mucus from the submucosal glands to the airway surface where cilia propel the mucus and trapped particles proximally toward the pharynx.
What is the submucosal gland ciliated duct connected to?
The ciliated duct connects the collecting ducts of submucosal glands to the ciliated respiratory epithelium lining the airway lumen.
Why is the submucosal gland ciliated duct clinically important?
