How does chemical co-ordination take place in animals ?


In animals, chemical coordination is achieved through the agency of hormones which function as chemical messengers or informational

molecules. Hormones are secreted by ductless glands in response to specific conditions or nervous stimulation. Timing and amount of a hormone

released are regulated by feed-back mechanism. After a meal, sugar level of blood rises. It is detected by pancreas. Pancreas responds by

producing hormone insulin from (3-cells of islets of Langerhans. Insulin causes glucose to be absorbed by all cells as well as get stored in liver

and muscles in the form of glycogen. As the level of glucose falls in blood, insulin secretion is reduced.
