- n. In physiology:
- n. In animal physiology, the process of preparing and separating substances by glandular activity. The product or secretion usually consists of substances previously existing in the blood, such as water, salts, etc., combined with others which have been elaborated by the glandular epithelium from more or less different substances in the blood. The secretion may be eliminated from the body as detrimental, as urine, or it may be used, as the digestive secretions, to serve requirements of the organism or (as the milk) those of its offspring. Secretions which are merely eliminated as detrimental are called
excretions. The act of secreting seems, in most instances at least, to be a vital act of the glandular epithelium, and is often, if not always, under direct nervous control.
- n. In vegetable physiology, the process by which substances are separated from the sap of vegetables. The descending sap of plants is not merely subservient to nutrition, but furnishes various matters which are secreted or separated from its mass, and afterward elaborated by particular organs. These secretions are exceedingly numerous, and constitute the great bulk of the solid parts of plants. They have been divided into— general or nutritious secretions, the component parts of which are gum, sugar, starch, lignin, albumen, and gluten; and special or non-assimilable secretions, which may be arranged under the heads of acids, alkalis, neuter principles, resinous principles, coloring matters, milks, oils, resins, etc.
- n. A substance or product secreted, or elaborated and emitted.
- n. Synonyms Excretion, Secretion. See excretion.
- n. A mineral deposit formed in a fissure or cavity by growth inward from the walls: contrasted with concretion, which grows outward from a nucleus.

- n. The act of secreting or concealing.
- n. (Physiol.) The act of secreting; the process by which material is separated from the blood through the agency of the cells of the various glands and elaborated by the cells into new substances so as to form the various secretions, as the saliva, bile, and other digestive fluids. The process varies in the different glands, and hence are formed the various secretions.
- n. (Physiol.) Any substance or fluid secreted, or elaborated and emitted, as the gastric juice.
- n. the organic process of synthesizing and releasing some substance
- n. a functionally specialized substance (especially one that is not a waste) released from a gland or cell

“The precise mechanism of melatonin secretion in the body is not well understood.”
“Basically, the evidence points to it being carbohydrates — sugar, flour and starchy vegetables — that cause the insulin secretion that put on fat.”
“By stimulating insulin secretion, carbohydrates make us fat and ultimately cause obesity.”
“The KATP channels (ATP-dependent potassium channels), which help to regulate insulin secretion in the beta cells, do not work properly in KATP HI.”
“Potassium channels, which regulate insulin secretion in the beta cells, do not work properly in the focal beta cells.”
“The unpleasant part of the experiment began when the participants had to spend half an hour in a draughty corridor after taking a hot bath, had to wear wet socks for the rest of the day, and were infected with nasal secretion from a cold sufferer.”
“Bad calories come from foods that overstimulate insulin secretion – bread, potatoes, pasta, sugar, tropical fruits.”
