What are hormones?

Hormones are indeed defined as chemical messengers produced by glands that regulate various body functions. They play a crucial role in coordinating complex processes such as growth, metabolism, reproduction, and mood regulation. Secreted directly into the bloodstream, hormones influence the activity of different organs and tissues. For example, insulin regulates glucose levels in the blood, while adrenaline affects the body's response to stress.

Understanding hormones as chemical messengers underscores their importance in maintaining homeostasis, as they can trigger responses at a cellular level to ensure that various body systems work harmoniously. This highlights the significant regulatory role hormones play in overall health and well-being.
