The different types of cellular functions n the human body are controlled and regulated by the specialized glands of the endocrine system. These glands are secretory organs which are divided into two main types:

Exocrine glands: They are the glands which functions by producing and secreting substances onto an epithelial surface with the help of the ducts. Sweat, salivary, mammary, lacrimal, sebaceous, and mucus are the glands of theexocrine system.
