How does chemical coordination take place in animals?
Solution:
The chemical coordination in animals takes place through hormones produced by the ductless glands i.e. endocrine glands of the body. Hormones are directly released into the bloodstream to reach the target site. Hormones control the behaviour of the target tissue.
Example: Adrenaline hormone is secreted by the adrenal gland which reaches the heart, lungs and gastrointestinal tract. The heart speeds up its pumping action so that more blood can be supplied to the limbs and facial muscles. However, the 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
