Also found in: Dictionary/thesaurus, Medical, Encyclopedia, Wikipedia | 0.07 sec. |
glandSpecialized organ of the body that manufactures and secretes enzymes, hormones, or other chemicals. In animals, glands vary in size from small (for example, tear glands) to large (for example, the pancreas), but in plants they are always small, and may consist of a single cell. Some glands discharge their products internally, endocrine glands, and others externally, exocrine glands. Lymph nodes are sometimes wrongly called glands. |
