What does the word secretion mean?
-
-
An organic function, which is chiefly executed in the glands, and consists in an elaboration or separation of the materials of the blood, at the very extremities of the arterial system, or rather of the vascular secretory system; and which differs in each organ according to its particular structure; hence the formation of different fluids ;-bile, saliva, urine, milk, &c. The secretions are of three kinds: - exhalant, follicular, and glandular. Simple se-cretions are those which exist ready-formed in the blood, and pass out of the vessels by an act of exosmose, whilst the more complicated are formed from the liquor sanguinis by cell-agency. The latter, alone, are, by some, called Secretions.
