The endocrine glands are the secretory glands that do not possess ducts. Instead, they secrete chemical molecules called hormones directly into the circulation. The hormones are secreted in minute quantity and play a vital role in maintaining homeostasis. The hormones act on the target organ that is usually far away in the body. The specificity of hormones on target organs is due to the presence of specific receptors on them.
