There are two main types of glands in the human body: exocrine glands and endocrine glands.
The main difference between these two types of glands is that exocrine glands secrete their products into ducts that lead to body cavities, internal organs, or the body's outer surface, while endocrine glands secrete hormones directly into the bloodstream.
Examples of exocrine glands include sweat glands, salivary glands, mammary glands, and sebaceous glands. Examples of endocrine glands include the pituitary gland, thyroid gland, pancreas, and adrenal glands. These glands are responsible for regulating a host of bodily functions such as metabolism, blood pressure, and reproductive processes.
Additionally, there are also other types of specialized glands, such as lacrimal glands (which produce tears), ceruminous glands (which produce earwax), and mucous glands (which produce mucus).
