Hormones are chemical messengers that are produced and secreted by glands in the endocrine system. They are carried by the bloodstream to different parts of the body, where they have specific effects on target cells or organs. Hormones play a vital role in regulating many physiological processes, including growth and development, metabolism, reproduction, and mood.

Insulin: regulates blood sugar levels

Thyroid hormones: regulate metabolism

Estrogen and progesterone: regulate female reproductive function

Testosterone: regulates male reproductive function and muscle mass

Cortisol: regulates the body’s response to stress

Adrenaline: triggers the “fight or flight” response in response to stress or danger.
