Hormones are non-nutrient chemicals that act as intercellular messengers and are produced in trace amounts. The endocrine glands and hormone-producing diffused tissues or cells located in different parts of our body constitute the endocrine system. Pituitary, pineal, thyroid, adrenal, pancreas, parathyroid, thymus, and gonads (testis in males and ovary in females). Some other organs, e.g., gastrointestinal tract, liver, kidney, the heart also produce hormones.
Hormones are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions. Hormones also play important role in plants. Plant hormones are small organic compounds, synthesized by specific plant cells or tissues, promote or inhibit the growth and developmental processes in plants that are active at low concentrations.
