Imagine your body is a giant kingdom with many different jobs to be done. Hormones are like the royal messengers, carrying messages from one part of the body to another to keep everything running smoothly.

• Other Names: You might not hear other names for hormones very often, but sometimes scientists refer to specific hormones by their chemical namesImagine you’re in a giant store with shelves full of ingredients, but the labels aren’t written in English! That’s kind of what it’s like for scientists and doctors dealing with all the different chemicals in the world. • Other Names: You might not hear “chemical names” used very often in everyday… Read More.

What do hormones do?

• Hormones travel through your bloodstream, delivering messages that tell your organsIn the context of the body, an organ is a distinct part made up of different tissues (groups of similar cells working together) that are organized to perform one or more specific functions.

Hormones vs. VitaminsA vitamin is an organic molecule, which means it’s a naturally occurring compound made up mostly of carbon. Our bodies need vitamins in small amounts to function properly. They help with many important jobs, including: • Building and maintaining healthy bones, teeth, and skin • Converting food into energy •… Read More and MineralsA mineral is a naturally occurring, inorganic solid substance with a definite chemical composition and an orderly crystalline structure. Unlike vitamins, which are organic (made by living things), minerals come from the earth and don’t contain carbon as a main component (think rocks like salt.) The Word “Mineral”: A Long… Read More

• Vitamins and minerals are essential nutrientsEssential nutrients are like the irreplaceable actors in a play – your body absolutely needs them to function properly.

You typically get them from food.
• Hormones, on the other hand, are produced by your body’s glands (like the thyroidThe thyroid, a small butterfly-shaped gland located in the neck just below the Adam’s apple, plays a vital role in the body by producing hormones (chemical messengers) that regulate many essential processes. Often compared to a factory manager overseeing workers, the thyroid ensures the body’s organs, such as the heart,… Read More or pituitary gland).
• While both are important for health, they work in different ways.

EtymologyEtymology is the study of the origin and history of words. It’s like detective work, tracing how words have changed over time and moved between languages. Think of it like this: • Words have a long history, just like old family stories. • Etymology digs into those stories to see… Read More (Word OriginsWhat is an origin? An origin is the starting point, the place or source where something begins. It’s like the very first chapter in the story of that thing.
