[1] Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, prostate and mucous.

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.

Exocrine sweat glands are part of the integumentary system; they have eccrine and apocrine types.

Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland.

[1] Depending on how their products are secreted, exocrine glands are categorized as merocrine, apocrine, or holocrine.
