what can hormone chemical messengers do
Dunn is an associate of the Center for Investigative Reporting. Hormones are chemical messengers that travel throughout the body coordinating complex processes like growth, metabolism, and fertility. They can influence the function of the immune system, and even alter behavior.Before birth, they guide development of the brain and reproductive system.ignaling ends when the circulating hormones are broken down and excreted by the body. Hormone disrupting chemicals, or endocrine disruptors, can act at any point along this hormone signaling pathway. Some are hormone mimics: they bind the receptor and send a false signal-one not commanded by the brain.
