Digestion, Absorption, & Transport (Chapter 3)

Delve into the intricate processes of how our bodies handle food with our comprehensive online course, “Digestion, Absorption, & Transport (Chapter 3).” This course is tailored for students, health professionals, and anyone curious about the journey food takes from ingestion to cellular utilization. Gain a deep understanding of the digestive system, the mechanisms of nutrient absorption, and the transport systems that deliver nutrients throughout the body.

Course Highlights:

1. Introduction to the Digestive System:
   • Overview: Understand the overall structure and function of the digestive system.
   • Key Organs: Learn about the major organs involved in digestion, including the mouth, esophagus, stomach, small intestine, and large intestine.
2. Mechanical and Chemical Digestion:
   • Mechanical Processes: Explore how mechanical actions like chewing and peristalsis aid in the breakdown of food.
   • Chemical Processes: Understand the role of digestive enzymes and acids in breaking down macronutrients into absorbable units.
3. Digestive Secretions:
   • Saliva: Learn about the components of saliva and its role in the initial stages of digestion.
   • Gastric Juice: Explore the composition and function of gastric juice in the stomach.
   • Pancreatic Juice and Bile: Understand how pancreatic enzymes and bile contribute to digestion in the small intestine.
4. Nutrient Absorption:
   • Absorptive Surface: Discover the structure and function of the small intestine’s absorptive surface, including villi and microvilli.
   • Mechanisms of Absorption: Learn about different mechanisms of nutrient absorption, such as passive diffusion, facilitated diffusion, active transport, and endocytosis.
5. Nutrient Transport:
   • Bloodstream vs. Lymphatic System: Understand the pathways for transporting water-soluble and fat-soluble nutrients.
   • Transport Proteins: Learn about the role of transport proteins in moving nutrients across cell membranes.
6. Macronutrient Breakdown and Absorption:
   • Carbohydrates: Explore the digestion and absorption of carbohydrates from polysaccharides to monosaccharides.
   • Proteins: Understand the breakdown of proteins into amino acids and their absorption.
   • Fats: Learn about the emulsification of fats by bile, their digestion by lipases, and absorption as fatty acids and monoglycerides.
7. Micronutrient Absorption:
   • Vitamins and Minerals: Discover how different vitamins and minerals are absorbed and utilized by the body.
   • Factors Affecting Absorption: Understand how factors like pH, presence of other nutrients, and health of the digestive tract influence micronutrient absorption.
8. Water and Electrolyte Balance:
   • Water Absorption: Learn about the mechanisms of water absorption in the small and large intestines.
   • Electrolyte Balance: Understand the absorption and regulation of key electrolytes like sodium, potassium, and chloride.
9. Digestive Health and Disorders:
   • Common Digestive Disorders: Explore conditions such as GERD, IBS, celiac disease, and lactose intolerance.
   • Impact on Absorption: Learn how these disorders affect digestion and nutrient absorption.
10. Interactive Learning and Assessment:
    • Case Studies: Engage in case studies that illustrate real-life applications of digestion, absorption, and transport principles.
    • Quizzes and Assignments: Participate in quizzes and assignments to test your knowledge and reinforce learning.
    • Peer Discussions: Join online forums and discussions to exchange insights, experiences, and best practices with fellow learners.
