How does chemical coordination take place in animals?

Explanation

Chemical coordination in animals is controlled by endocrine system. The endocrine system coordinates the activities of the body with the nervous system. Endocrine system comprises of endocrine glands and hormones. Hormones are chemical substances produced by the endocrine glands. They act as messengers between the nervous system and the body organs. Hormones are released directly into the nearby blood vessels, from where they are carried to specific tissues or organs called target tissues or target organs.
There are many glands and hormones in different animal species. Different endocrine glands secrete different hormones. In the target tissues, hormone triggers a specific biochemical or physiological activity. Hormones have a wide range of effects and modulate many different body processes like regulation of blood glucose, hunger, metamorphosis, stress, growth and so on.
