How does chemical coordination take place in animals?
Solution:
The chemical coordination in animals take place through hormones produced by the ductless glands i.e. endocrine glands of the body. Hormones are directly released into blood stream to reach the target site. Hormones control the behavior of the target tissue.
Example: Adrenaline hormone is secreted by the adrenal gland which reaches the heart, lungs and gastro intestinal tract. Heart speeds up its pumping action so that more blood could be supplied to the limbs and facial muscles. But activity of the GI tract is slowed down to ensure better blood supply in limbs. Thus, adrenalin prepares the body for a fight or flight situation
