Exocrine glands are specialized organs that produce and secrete substances through ducts to specific locations in the body. These substances can include enzymes, sweat, saliva, and mucus. Common examples of exocrine glands include the salivary glands, sweat glands, and pancreas, which plays a crucial role in digestion. Unlike endocrine glands, which release hormones directly into the bloodstream, exocrine glands transport their secretions to the surface of organs or into body cavities. This allows for targeted functions, such as aiding in digestion or regulating body temperature through sweat production.
