    • n secretion In physiology:
    • n secretion 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 secretion 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.
