Explain compound gland?

A compound gland is a type of gland that is made up of multiple secretory units, each with its own duct that carries the secretions to a specific location. These glands are typically larger and more complex than simple glands, which have a single secretory unit. Compound glands can be found in various parts of the body, such as the salivary glands, mammary glands, and sweat glands. They are important for producing and releasing various substances, such as enzymes, hormones, and sweat, that are necessary for the body's functioning.
