Exocrine gland
|
|
Exocrine glandA gland that secretes a substance out through a duct. The exocrine glands include the salivary glands, sweat glands and glands within the gastrointestinal tract. The exocrine glands are the "glands of external secretion."
RELATED TERMS--------------------------------------
Gland
An organ that releases a chemical. Endocrine glands are ductless and secrete hormones directly into the bloodstream. Exocrine glands secrete externally, either through a tube or duct.
Duct
A channel or passage through which fluids move.
Exocrine
Pertaining to a gland with a duct through which its secretion, for example, tears or saliva, passes.
Gastrointestinal
Having to do with the stomach and intestines.
SIMILAR TERMS--------------------------------------
Exocrine

Exocrine glands
Glands that secrete chemicals externally, either through a tube or duct.
Exocytosis
The process by which intracellular chemicals (including hormones) are released.
PREVIOUS AND NEXT TERMS--------------------------------------
Exercise, isometric
Exercise involving muscular contractions without movement of the involved parts of the body. Isometric exercise is one method of muscular exercise. In contrast, isotonic exercise occurs when a contracting muscle shortens against a constant load, as when lifting a weight.
Exercise, isotonic
Exercise when a contracting muscle shortens against a constant load, as when lifting a weight. Isometric exercise is one method of muscular exercise. In contrast, isotonic exercise is when muscular contractions occur without movement of the involved parts of the body.
Exercise, passive
Movement of the body, usually of the limbs, without effort by the patient. The patient is passive.
Exercise-induced asthma
Asthma that is "triggered" by vigorous physical activity. Exercise-induced asthma tends particularly to affect children and young adults (because of their high level of physical activity) but can occur at any age.
Exercise-induced bronchospasm
Also called exercise- induced asthma, this is asthma that is triggered by vigorous physical activity. Exercise-induced asthma tends particularly to affect children and young adults (because of their high level of physical activity) but can occur at any age.
Exocrine gland
Exogenous DNA
DNA originating outside an organism.
Exonuclease
An enzyme that cleaves nucleotide bases sequentially from the free ends of a nucleic acid (DNA or RNA).
Exopeptidase
An enzyme that catalyzes the cleavage of the terminal (last) or next-to-last peptide bond from a polypeptide or protein, releasing a single amino acid or dipeptide. By contrast, an endopeptidase catalyzes the cleavage of then internal peptide bonds within a polypeptide or protein.
Expectorant
A medication that helps bring up mucus and other material from the lungs, bronchi, and trachea. An example of as expectorant is guaifenesin which promotes drainage of mucus from the lungs by thinning the mucus and also lubricates the irritated respiratory tract. Sometimes the term "expectorant" is incorrectly extended to any cough medicine.
Expectoration
A big polysyllabic word for sputum or the act of bringing up and spitting out sputum.
