How does chemical coordination take place in animals?

(N/A) Chemical coordination in animals is mediated by hormones.
Hormones are chemical messengers that regulate various physiological processes in living organisms.
These substances are secreted by endocrine glands directly into the bloodstream.
The regulation of physiological processes,as well as control and coordination via hormones,is collectively known as the endocrine system.
In animals,the nervous system works in conjunction with the endocrine system to effectively control and coordinate complex physiological activities.
