There are basically 3 types of salivary (spit) glands and secretions they produce:
- Serous (watery); mostly in the parotid gland (the largest salivary gland, its duct comes out at the level of the upper second molar) and glands of von Ebner
- Mucous (thick); in the palatine and posterior lingual glands. They generally aid in swallowing.
- Mixed; in the sublingual glands, submandibular glands (the most prolific producer of saliva), and the anterior sublingual glands. These glands (generally) secrete around the tongue.
