常见问题

What is the submucosal gland collecting duct?
A submucosal gland collecting duct is an intermediate duct that gathers secretions from multiple acini of submucosal glands before delivering them to the ciliated terminal duct.
Where is the submucosal gland collecting duct located?
Located within the submucosa of the respiratory tract, these ducts are positioned between the glandular acini and the surface ciliated ducts.
What is the function of the submucosal gland collecting duct?
The collecting duct aggregates mucus and serous secretions from scattered acini into a unified stream that flows toward the airway lumen.
What is the submucosal gland collecting duct connected to?
The collecting duct connects multiple acini proximally to the ciliated terminal duct distally, forming the functional duct system of submucosal glands.
Why is the submucosal gland collecting duct clinically important?
Disease affecting these ducts, such as in cystic fibrosis or chronic inflammation, impairs mucus clearance and predisposes to recurrent infections.
