Exocrine glands are glands that secrete substances onto an epithelial surface by way of a duct. [1] Examples of exocrine glands include sweat , salivary , mammary , ceruminous , lacrimal , sebaceous , prostate and mucous .

Glands are divided based on their function into two groups: Here is a diagram that shows the differences between endocrine and exocrine glands. The major difference is that exocrine glands secrete substances out of the body and endocrine glands secrete substances into capillaries and blood vessels.
The pancreas is an organ of the digestive system and endocrine system of vertebrates.In humans, it is located in the abdomen behind the stomach and functions as a gland.The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function.
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
However, there is only ever a single thyroid gland in most mammals, and the shape found in humans is common to many other species. [104] In larval lampreys, the thyroid originates as an exocrine gland, secreting its hormones into the gut, and associated with the larva's filter-feeding apparatus. In the adult lamprey, the gland separates from ...
Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen.
Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood. The major glands of the endocrine system include the pineal gland , pituitary gland , pancreas , ovaries , testicles , thyroid gland , parathyroid gland , hypothalamus and adrenal glands .
