salt gland
Low-frequency (Specialist)Technical / Scientific
Definition
Meaning
A specialized gland, found in certain animals, that secretes a concentrated salt solution to maintain osmotic balance.
In a biological context, any glandular structure adapted for excreting excess salt from the body. In metaphorical use, can refer to any system or mechanism for purging or managing an unwanted excess.
Linguistics
Semantic Notes
A compound noun where 'salt' modifies the type of 'gland'. The primary meaning is biological, with almost no figurative use in general discourse.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like '*солёная железа*'. The correct translation is 'солевая железа'.
- Do not confuse with 'salivary gland' (слюнная железа).
Common Mistakes
- Misspelling as 'salt gland*e*' (adding an extra 'e').
- Using it as a general term for any gland, e.g., 'sweat gland'.
- Incorrect plural: 'salts gland' instead of 'salt glands'.

FAQ
Frequently Asked Questions
Its primary function is osmoregulation—removing excess salt from an animal's body to maintain a healthy water and ion balance, especially in marine environments.
No, humans do not possess salt glands. We excrete excess salt primarily through our kidneys via urine and through sweat glands, which are different in structure and function.
In most seabirds, salt glands are located in grooves or ducts above the eyes, in the supraorbital region. The secreted brine often drips from the tip of the beak.
No, it is a low-frequency, specialised term used almost exclusively in biological and zoological contexts. It is not part of general everyday vocabulary.
