MICROANATOMY

Detailed explanation-1: -A gland can be classified as an endocrine gland, a ductless gland that releases secretions directly into surrounding tissues and fluids (endo-= “inside”), or an exocrine gland whose secretions leave through a duct that opens to the external environment (exo-= “outside”).

Detailed explanation-2: -The multicellular exocrine glands known as serous glands develop from simple epithelium to form a secretory surface that secretes directly into an inner cavity. These glands line the internal cavities of the abdomen and chest and release their secretions directly into the cavities.

Detailed explanation-3: -Exocrine glands release their contents through a duct that leads to the epithelial surface. Mucous, sweat, saliva, and breast milk are all examples of secretions from exocrine glands. They are all discharged through tubular ducts.

Detailed explanation-4: -Exocrine glands release their secretory products into a duct which opens into a specific part of the body (e.g. skin, stomach, respiratory tract). Some examples of exocrine glands include the sweat glands, salivary glands, and lacrimal glands, among others.
