The function of the white serous secretion is not known.

The parotid gland makes serous secretions only.

The acini contain only serous cells and produce a watery serous secretion.

These glands empty their serous secretion into the base of the moats located around the foliate and circumvallate papillae.

Lamina propria also contains glands with the ducts opening on to the mucosal epithelium, that secrete mucus and serous secretions.

The incoming odorants are made soluble by the serous secretion from Bowman's Glands, located in the lamina propria of the mucosa.

Ducts of lingual salivary glands, referred to as Von Ebner's glands empty serous secretion into the base of the circular depression (moats).

Acute adenoiditis is characterized by fever, runny nose, nasal airway obstruction resulting in predominantly oral breathing, snoring and sleep apnea, rhinorrhea with serous secretion in viral forms and mucous-purulent secretion in bacterial forms.
