Why is the posterior pituitary not considered an endocrine gland?

What are two examples of exocrine glands?

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.

What are the major glands of the endocrine system?

What is the main function of exocrine glands?

Exocrine glands play a key role in the physiology of many organ systems from the skin to the pancreas, providing the body with a method to release secretions containing proteins, mucus, and other products to epithelial surfaces around the body.

Why is the exocrine gland not part of the endocrine system?

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. ... These hormones affect many parts of the human body.
