What are hormones primarily known as?

Hormones are primarily known as the body's chemical messengers because they play a crucial role in regulating various physiological processes throughout the body. They are produced by glands in the endocrine system and released directly into the bloodstream, where they travel to target organs and tissues to elicit specific responses. Hormones influence a wide range of functions, including metabolism, growth and development, immune system response, and mood regulation.

This classification as chemical messengers highlights their importance in communication between different parts of the body, allowing for the coordination of complex bodily functions. Hormones can affect processes even at very low concentrations, demonstrating their potency and significance in maintaining homeostasis and overall health. Understanding this role is fundamental in the fields of biology and medicine, as imbalances in hormone levels can lead to various health issues.
