Hormones are non nutrient chemicals, which act as intracellular messengers and are produced in trace amounts. Endocrine cells are present in different parts of the gastrointestinal tract, e.g., gastrin, secretin, GIP. Atrial wall of our heart secretes a peptide hormone called ANF (Atrial Natriuretic Factor), RH/IH are produced by hypothalamus. Adenohypophysis is not directly under neural control, it is under the control of hypothalamic hormones, brought by portal system.

Introduction:
Hormones are chemical messengers produced by endocrine glands that regulate various physiological processes in the body. They are essential for maintaining homeostasis and coordinating the functions of different organ systems.
Non-nutrient:
Hormones are non-nutrient molecules that are not used for energy or growth but instead act as signaling molecules.
Intracellular messengers:
Hormones generate intracellular messengers that transmit signals within cells. These messengers activate various signaling pathways, which ultimately lead to changes in gene expression, protein synthesis, and cellular function.
Produced in trace amounts:
Hormones are produced in trace amounts by endocrine glands and are released into the bloodstream. Even small changes in hormone levels can have significant effects on the body.
Conclusion:
In summary, hormones are non-nutrient molecules that generate intracellular messengers and are produced in trace amounts. They play a crucial role in regulating various physiological processes and maintaining homeostasis in the body.
