Secretory products refer to substances produced and released by cells or glands in the body. These can include hormones, enzymes, mucus, and various proteins. For example, endocrine glands secrete hormones like insulin, while exocrine glands release substances such as saliva or digestive enzymes. Each type of secretory product plays a crucial role in regulating bodily functions and maintaining homeostasis.
Secretory cells are specialized to produce and release specific substances, such as hormones, enzymes, mucus, or neurotransmitters. They typically have a large amount of rough endoplasmic reticulum and Golgi apparatus to support synthesis and packaging of the secretory products. They often have specialized structures like secretory vesicles or ducts to transport and release the secreted substances to their target locations.
The part of a cell that acts as a sac to store excretory or secretory products is called a vesicle. Vesicles are small membrane-bound sacs that transport and contain various substances within the cell, including proteins, lipids, and waste products. They play a crucial role in processes such as secretion, metabolism, and cell signaling.
An adenomere is the functional unit in a salivary gland, consisting of all the secretory cells that release their products into a single intralobular duct.
This process is called holocrine secretion, where the entire cell containing the secretory product ruptures to release its contents. This differs from merocrine secretion, where secretory products are released through exocytosis without cell damage.
The secretory epithelium is a part of the skin and associated with the sweat glands.
To deliver secretory products to the extracellular spaces.
Golgi body is a cell organell, which is a centre for dipatchment of secretory products

Modes of Secretionof exocrine glandsSecretory cells of exocrine glands release their products into ducts in three different ways. The mode of secretion can be classified as merocrine, apocrine, or holocrine.Cells that secrete products via the merocrine method form membrane-bound secretory vesicles internal to the cell. These are moved to the apical surface where the vesicles coalesce with the membrane on the apical surface to release the product. Most glands release their products in this way.In those glands that release product via the apocrinemethod, the apical portions of cells are pinched off and lost during the secretory process. This results in a secretory product that contains a variety of molecular components including those of the membrane. Mammary glands release their products in this manner.The third type of secretory release, holocrine, involves death of the cell. The secretory cell is released and as it breaks apart, the contents of the cell become the secretory product. This mode of secretion results in the most complex secretory product. Some sweat glands located in the axillae, pubic areas, and around the areoli of the breasts release their products in this manner. Sebaceous glands also are of this type.
The secretory system does not really exist. There is a secretory mechanism that is part of the endocrine system, and that secretes hormones into the blood stream.
This process is called holocrine secretion, where the entire cell containing the secretory product ruptures to release its contents. This differs from merocrine secretion, where secretory products are released through exocytosis without cell damage.

The type of exocrine gland you are referring to is a merocrine gland. Merocrine glands release their secretory products by exocytosis without losing any part of the cell. Examples include salivary glands and sweat glands.
