Glands

A gland is a specialized structure consisting of differentiated cell or cells. Any specially differentiated cell or cells elaborating chemical substances when the substances are useful for metabolic processes is said to be secreting. When glands elaborate non-useful substances, the process is termed excretion.

Glands can either be unicellular or multicellular. An example of a unicellular gland is the goblet cell which secretes mucus. A broad classification of glands recognize two types of glands- exocrine and endocrine glands
