Digestion and Absorption: Human Physiology and Gut Health

Have you ever wondered how your body transforms the food you eat into vital energy and cellular building blocks? Understanding the human digestive system is the foundation of biology, nutrition, and personal wellness. This text-based course guides you through the entire digestive journey, from the first bite to nutrient assimilation. You will gain a clear, science-backed understanding of both mechanical and chemical digestion, as well as the crucial role of the modern gut microbiome. What you'll learn: * Understand the anatomical structure and functions of the digestive tract. * Analyze how mechanical processes and chemical enzymes break down macronutrients. * Explore the mechanisms of nutrient absorption in the small and large intestines. * Examine the role of the gut microbiome and its impact on overall systemic health. * Learn about common digestive issues and how lifestyle factors influence gut motility. * Practice applying physiological concepts to real-world nutritional choices. The course begins with foundational terminology and the basic anatomy of the gastrointestinal tract before tracing the step-by-step pathway of food digestion and absorption. You will read detailed explanations of enzymatic reactions and modern gut health concepts. This course is designed for beginners, students of biology or nutrition, and anyone curious about human physiology. No prior scientific background is required.
