Question
Explain why hormones are known as chemical messengers.
Answer
Hormones are known as chemical messengers because they are signalling molecules that are produced by glands or specialized cells in the body and are transported through the bloodstream to target tissues and organs, where they exert their effects by binding to specific receptors.
Like messengers carrying a message from one person to another, hormones carry information from one part of the body to another to coordinate and regulate various physiological processes. This enables hormones to communicate with distant cells and organs and allows them to affect a wide range of physiological functions, such as growth and development, metabolism, and stress responses.
