Write down the differences between:
Exocrine Glands and Endocrine Glands

Differences between Exocrine and Endocrine Glands are as follows:

Exocrine Glands:Exocrine Glands are the glands that secrete their products ( excluding harmones and other chemical messengers) into ducts (duct gland) which lead directly into the external environment.They are closer to the target cells.Their secretion remains inside the duct and reach the target cells directly.Their secretions are called Enzymes.Examples: pancreas , salivary glands etc.Endocrine Glands:Endocrine Glands are the glands of endocrine system that secrete their products, harmones directly into the blood rather than through a duct.They may be far from the target cells.Their secretion pass to all parts of the body but show effect on the target cells only.Their secretion are called harmones.Example: pituitary gland , Testes etc.
