Значение термина gland в knolik
gland - gland
gland - An organ (sometimes a single cell) whose main function is to build up one or more specific chemical compounds (secretions) which are passed to the outside of the gland. (Bot.). Superficial, discharging secretion externally, e.g. glandular hair (lavender), nectary, hydathode; or embedded in tissue, occurring as isolated cells containing the secretion, or as layer of cells surrounding intercellular space (secretory cavity or canal) into which secretion is discharged, e.g. resin canal of pine. (Zool.). Most glands are exocrine, i.e. their secretions are discharged, usually through a tube or duct, on to a surface, either the outer (epidermal) surface of the body, e.g. sweat-glands of mammals, or the inner surface of the gut, e.g. digestive glands. There are also in some animals endocrine glands, secreting hormones directly into blood.
