All about Hormones
Hormones are chemical messengers released by glands into the bloodstream. They travel to target organs and control processes such as growth, mood, hunger and sleep.
Adrenaline is a hormone that prepares the body to react quickly when you feel frightened or excited.
They are made by glands, such as the thyroid and adrenal glands, and they travel through the blood. Only certain cells respond to each hormone, like a key that fits one particular lock.
Hormones control many important things. They affect how fast you grow, how hungry you feel, how you sleep and how your mood changes. During puberty, hormones cause many changes in the body as a person grows from a child into an adult.
