Glands
Glands
Glands (/ɡlændz/) are a group of cells in an organism's body that synthesizes substances (such as hormones) for release into the bloodstream (endocrine glands) or into cavities inside the body or its outer surface (exocrine glands).
Etymology
The term "gland" has been derived from the Latin word 'glandula', which means acorn. It was first used in the 18th century to describe the shape of certain organs.
Types of Glands
There are two main types of glands in the human body: Endocrine glands and Exocrine glands.
- Endocrine glands are ductless glands that produce and secrete hormones directly into the bloodstream. Examples include the pituitary gland, thyroid gland, and adrenal glands.
- Exocrine glands secrete their products into ducts that lead to the target place. Examples include sweat glands, salivary glands, and mammary glands.
Function of Glands
Glands perform a variety of functions in the body, from the production of hormones and enzymes to the secretion of fluids. The specific function of a gland depends on the type of gland and its location in the body.
