Chemical coordination takes place in animals with the help of hormones. Hormones are the chemical fluids that are secreted by the glands of the endocrine system. Hormones regulate the overall growth and development of animals.
Types of glands
There are two types of glands helping in the coordination which are exocrine and endocrine glands
Exocrine glands – Secrete juices through a duct.
Example – The salivary gland
Endocrine glands – Secrete juices directly in the bloodstream. They secrete hormones called chemical messengers.
Example – Thyroid gland
The nervous system including the endocrine system controls and as well as coordinates the physiological process in the human body.
