The developing body has a thousand tasks to accomplish. It needs to lengthen the bones, distribute hair here and there, and enlarge the chest… To manage to complete all these tasks, it has the support provided by reliable and diligent partners: the hormones!
Hormones are chemical substances that transmit messages. They are produced in specific organs or groups of cells, the endocrine glands, which release them into the blood. As they travel through the circulatory system, hormones manage to deliver the message they carry to even the most remote corner of the body. The recipients of these messages are the cells, which, once they receive the command, execute it immediately.
