Exocrine gland Exocrine gland Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous. Exocrine glands are one of two types of glands in the human body, the other being endocrine glands, which secrete their products directly into the bloodstream. The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products—bile and pancreatic juice—into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream.

Esophageal gland Esophageal gland The esophageal glands are glands that are part of the digestive system of various animals, including humans. Esophageal glands in humans are a part of a human digestive system. They are a small compound racemose exocrine glands of the mucous type. There are two types: Each opens upon the surface by a long excretory duct. Oesophageal gland is enlarged in large monoplacophoran species. Oesophageal gland or oesophageal pouch is a part of the digestive system of some gastropods. Oesophageal gland or pouch is a common feature in so-called basal gastropod clades, including Patelloidea, Vetigastropoda, Cocculiniformia, Neritimorpha and Neomphalina.
