Course description

he Hormones of the Kidney, Duodenum & Jejunum Certificate Course is designed to uncover the lesser-known but highly significant hormonal activities of the excretory and gastrointestinal systems. Participants will study how these organs act not only as functional systems for filtration and digestion but also as active endocrine organs influencing metabolism, blood pressure, red blood cell formation, and digestive regulation.

The course provides a detailed overview of kidney hormones such as renin, erythropoietin, and calcitriol, explaining their roles in blood pressure regulation, oxygen transport, and calcium metabolism. It also examines duodenal and jejunal hormones — including secretin, cholecystokinin (CCK), gastric inhibitory peptide (GIP), and motilin — with a focus on how they coordinate digestive secretions and nutrient assimilation.

Learners will explore the interaction between nutrition, gut health, and endocrine signaling, understanding how diet and lifestyle factors affect these hormones and contribute to systemic balance. Through case discussions and visual lectures, participants will gain both theoretical and applied knowledge relevant to clinical nutrition, physiology, and health sciences.

What will i learn?

• Describe the endocrine functions of the kidney, duodenum, and jejunum.
• Identify the major hormones secreted by these organs and their physiological roles.
• Explain the regulatory mechanisms of renin, erythropoietin, and calcitriol in maintaining fluid, blood pressure, and calcium balance.
• Understand the digestive and metabolic roles of secretin, CCK, GIP, and related intestinal hormones.
• Analyze how nutrition and gut function influence hormonal activity in these organs.
• Apply hormonal knowledge to interpret physiological and clinical implications in nutrition and health management.
