Hormone

What Are Hormones?

Hormones are special tiny messengers in our bodies. They help different parts talk to each other. Animals, plants, and even fungi use hormones to share important messages. These messages help our bodies grow, stay healthy, and do many things we need to do every day.

How Do Hormones Work?

Hormones are made in special places in our bodies called endocrine glands. These glands send hormones into our blood. The hormones travel to other parts of the body and tell cells what to do. For example, they can help us grow, tell us when we are hungry, or even help us feel happy!

In plants, hormones help them grow from tiny seeds into big trees or flowers. They know just when to grow leaves, flowers, or fruits.

Why Are Hormones Important?

Hormones help keep our bodies balanced and working well. They help with many things, like how we grow, how we sleep, and even our moods. When everything is just right, our bodies stay healthy and strong.

Scientists have learned a lot about hormones. They discovered them by watching how animals and plants change when certain parts are missing. For example, a scientist named Arnold Berthold saw that roosters without certain parts acted differently. This helped him learn about a hormone called testosterone.
