ANATOMY

Detailed explanation-1: -A gland that makes substances such as sweat, tears, saliva, milk, and digestive juices, and releases them through a duct or opening to a body surface. Examples of exocrine glands include sweat glands, lacrimal glands, salivary glands, mammary glands, and digestive glands in the stomach, pancreas, and intestines.

Detailed explanation-2: -Eccrine sweat glands occur over most of the body and open directly onto the skin’s surface. Apocrine glands open into the hair follicle, leading to the surface of the skin. Apocrine glands develop in areas with many hair follicles, such as on the scalp, armpits and groin.

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 mechanisms by which exocrine glands release their secretions include merocrine, apocrine, and holocrine. Merocrine glands are the most common subtype. By definition, merocrine gland secretions exit the cell via exocytosis.

Detailed explanation-5: -Your exocrine system includes a series of glands all over your body. These glands secrete substances that help your organs function, including sweat, breast milk, mucus and oil. Your exocrine system is different from your endocrine system, in that it secretes these substances through ducts.
