Here's a breakdown:
* Gland: A specialized structure that synthesizes and releases substances (secretions) for use elsewhere in the body or for elimination.
* Secretion: The process of producing and releasing a substance from a cell or gland.
There are two main types of glands:
* Exocrine glands: These glands release their secretions through ducts (tubes) to a specific location, such as the surface of the skin or into a cavity. Examples include sweat glands, salivary glands, and mammary glands.
* Endocrine glands: These glands release their secretions (hormones) directly into the bloodstream, which then carries them to target cells throughout the body. Examples include the thyroid gland, pancreas, and adrenal glands.
