Enzyme-rich saliva comes from serous cells, which produce a watery secretion loaded with enzymes. In the mouth, amylase is secreted by serous components of the salivary system (for example, the parotid gland is predominantly serous and releases amylase to start starch digestion). Lipase, specifically lingual lipase, is produced by serous von Ebner’s glands on the tongue. Mucous glands, by contrast, mainly make mucus for lubrication and don’t provide digestive enzymes. Endocrine and lymph glands aren’t involved in producing digestive enzymes either. So the glands that secrete enzymes like lipase and amylase are serous glands.
