How is chemical co-ordination done in animals?

The endocrine system is involved in the chemical coordination. Here stimulated cells release a chemical compound (called hormones), which diffuse all around the original cell. The hormones are released into the blood which carry them to different parts of the body. When this hormone reaches specific target cells, which have special signals to detect this compound, these target cells would be able to recognise the information and even transmit it. The hormones used by multicellular organisms for control and coordination show a great deal of diversity in order to enable them to carry out various functions. The advantage of chemical signals is that it would reach all cells of the body and does not rely on specialised structures like nervous connections. Some examples of endocrine glands are pituitary, hypothalamus, adrenal, thyroid etc.
