Detailed explanation-1: -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-2: -Endocrine glands are ductless glands and release the substances that they make (hormones) directly into the bloodstream. These glands form part of the endocrine system and information on them is included in this website. There is another type of gland called an exocrine gland (e.g. sweat glands, lymph nodes).
Detailed explanation-3: -Examples of exocrine glands are sweat, salivary, sebaceous, mucous gland. An endocrine gland is a gland which secretes its products directly into the blood stream. Examples of endocrine glands are pituitary gland, ovaries, testes, thyroid gland, adrenal glands.
Detailed explanation-4: -A gland is an organ which involves secretion of chemical substances. Whereas, a duct is a tube-like structure which helps in transfering the secretions/cells, etc. to various body parts.
