MICROANATOMY

Detailed explanation-1: -What’s the difference between endocrine and exocrine glands? Exocrine glands secrete their substances through ducts onto your body’s surfaces. On the other hand, endocrine glands secrete their substances directly into your bloodstream. They’re called ductless glands.

Detailed explanation-2: -The key difference between the two types is that, whereas exocrine glands secrete substances into a ductal system to an epithelial surface, endocrine glands secrete products directly into the bloodstream [1].

Detailed explanation-3: -The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products-bile and pancreatic juice-into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream.

Detailed explanation-4: -Endocrine glands do not have ducts. Their secretions (hormones) are secreted into the blood stream. Because of this, the hormones can act over long distances, and reach any organ in the body to co-ordinate activity. Often there is a specific ‘target’ organ that the hormone acts on.

Detailed explanation-5: -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.
