Hormones are chemical messengers produced by glands in the endocrine system. They travel through the bloodstream to target cells and tissues, where they regulate a wide range of bodily functions. These functions include growth and development, metabolism, mood, sexual function, and reproduction. Hormones play a critical role in maintaining homeostasis, the stable internal environment necessary for life.

The endocrine system is a complex network of glands, including the pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries, and testes. Each gland produces specific hormones that have distinct effects on the body. For example, insulin, produced by the pancreas, regulates blood sugar levels. Thyroid hormones, produced by the thyroid gland, control metabolism. Estrogen and testosterone, produced by the ovaries and testes respectively, are responsible for sexual development and reproduction.

Hormone levels can fluctuate throughout life due to various factors such as age, stress, diet, and illness. Imbalances in hormone levels can lead to a variety of health conditions. For instance, a deficiency in insulin can result in diabetes, while an overproduction of thyroid hormones can cause hyperthyroidism. The study of hormones and their effects is known as endocrinology. Understanding hormone function is crucial for diagnosing and treating many diseases.
