उत्तर
In human body there are two types of glands - exocrine and endocrine. The exocrine glands have ducts and discharge their secretions through them, e.g., salivary glands, liver, etc. The endocrine glands are those which do not possess any duct and discharge their secretion (hormones) directly into the blood stream to send them to the various parts of the body. The endocrine glands and their secretion (hormones) constitute the endocrine system which along with nervous system coordinates the activity of various parts of the body.
