How does chemical coordination take place in animals?
Answer
View full question & answer→Hormones are the long range chemical messengers that are released into blood by endocrine gland in response to some signal. These hormones exert their effect on the target cells present distantly from their site of release. These hormones serve the function of chemical coordination in animals.
Hormones are released into the blood stream and can reach all cells but they affect only target cells. This is followed by generation of stimulus specific biochemical or physiological activity. In this way, hormones regulate functioning of different organs and tissues. Each hormone is under regulation of feedback mechanism which in turn ensures reliability of the system.
