exocrine
C2Formal, Technical/Scientific
Definition
Meaning
Relating to glands that secrete their products via ducts directly into a specific location or onto a surface, rather than into the bloodstream.
Can be used metaphorically to describe systems or processes that deliver outputs to a specific, localised external destination, as opposed to a general, systemic one.
Linguistics
Semantic Notes
The term is almost exclusively used in biological, medical, and anatomical contexts. It is defined in opposition to 'endocrine'. It can function as both an adjective and a noun ('exocrine gland' vs. 'the exocrines').
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning, spelling, or usage. Pronunciations differ slightly (see IPA).
Connotations
Purely technical and neutral in both varieties.
Frequency
Extremely low frequency in general discourse, but standard within relevant scientific fields in both the UK and US.

Context Usage
Business
Virtually never used.
Academic
Core terminology in human/animal biology, anatomy, physiology, and medical studies.
Everyday
Almost never encountered outside of educational or medical contexts.
Technical
Essential and precise term in endocrinology, gastroenterology (e.g., exocrine pancreas), and dermatology (e.g., sweat glands).
Examples
By Part of Speech
adjective
British English
- The exocrine function of the pancreas is to deliver digestive enzymes to the duodenum.
- Sweat glands are a classic example of exocrine glands.
American English
- The pancreas has both endocrine and exocrine roles.
- Exocrine secretions, like saliva, exit the body via ducts.
Examples
By CEFR Level
- The liver is an exocrine gland because it makes bile.
- Doctors were concerned about the patient's exocrine pancreatic insufficiency.
- The study compared the gene expression profiles of endocrine and exocrine cells within the same organ.
Learning
Memory Aids
Mnemonic
Think: EXO means 'outside' and CRINE relates to 'secrete'. Exocrine glands secrete substances OUTSIDE (via ducts to a specific location).
Conceptual Metaphor
LOCALISED DELIVERY SYSTEM (like a postal service delivering a parcel to a specific address) vs. ENDOCRINE as BROADCAST SYSTEM (like a radio signal).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'экзокринный' (correct) and 'эндокринный' (endocrine). The 'exo/endo' distinction is critical.
- Avoid literal translation in non-scientific contexts as it will sound jarring.
Common Mistakes
- Confusing 'exocrine' with 'endocrine'.
- Pronouncing it as /ˌɛksəˈkriːn/ (like 'crine' in 'crime').
- Using it as a general synonym for 'secretory'.

FAQ
Frequently Asked Questions
Exocrine glands secrete substances via ducts to a specific, localised site (e.g., skin, digestive tract). Endocrine glands secrete hormones directly into the bloodstream for systemic distribution.
The pancreas is a prime example; its exocrine portion secretes digestive enzymes into the small intestine via the pancreatic duct.
Extremely rarely. Its use is almost entirely confined to scientific and medical terminology. Metaphorical use is highly specialised and uncommon.
It is fundamental to understanding how the body regulates and delivers different types of secretions. Diseases and treatments often target one system specifically (e.g., cystic fibrosis affects exocrine function).
