Detailed explanation-1: -What are exocrine glands? Exocrine glands release (secrete) substances through openings (ducts) onto your body surfaces. Exocrine glands secrete sweat, tears, saliva, milk and digestive juices. A gland is a unit of cells that work together to create and secrete these substances.

Detailed explanation-2: -4. The exocrine glands are located in the intestinal wall, gastrointestinal tract, or outside such as salivary glands, liver, pancreas, etc.

Detailed explanation-3: -There is another type of gland called an exocrine gland (e.g. sweat glands, lymph nodes). These are not considered part of the endocrine system as they do not produce hormones and they release their product through a duct.

Detailed explanation-4: -The three types of exocrine glands include the apocrine, holocrine, and merocrine glands. The apocrine glands release a portion of their own cells with the substance they secrete. An example of an apocrine gland is the mammary gland, which secretes milk into the ducts of the breasts.
