CIE IGCSE Biology 0610 — Chapter 7: Human Nutrition — Content Review Guide for Revision
CIE IGCSE Biology 0610: Human Nutrition Content Review Guide (Ch. 7)Master digestion, absorption, and balanced diet—with precision and clarity.Human nutrition is a core topic that appears consistently across both Paper 2 (MCQ) and Paper 4 (Extended Theory). This focused content review guide delivers everything you need to understand the digestive system, enzymes, bile, villi absorption, and the components of a balanced diet—with the exact language examiners expect.What’s Inside: Complete Digestive System Overview: Organs and their functions, from mouth to anus—including key roles of the stomach, pancreas, liver, and small intestine. The 6 Essential Digestive Enzymes: A complete table covering salivary amylase, pancreatic amylase, maltase, pepsin, trypsin, and lipase—with organ, substrate, product, and optimum pH for each. Bile—What It Is and What It Does: Clear explanation of bile production (liver), storage (gall bladder), and its two critical functions: emulsification of fats and neutralisation of stomach acid. Includes the exam-critical distinction: bile is NOT an enzyme. Villi Structure & Absorption: Detailed breakdown of villi adaptations—finger-like projections, microvilli, thin epithelium, capillary network, lacteal, and mitochondria. Includes the route of absorbed nutrients (glucose/amino acids to blood; fatty acids/glycerol to lymph). Balanced Diet—7 Food Groups: Complete table covering carbohydrates, proteins, lipids, vitamins, minerals, fibre, and water—with sources, functions, and deficiency effects. Key Vitamins & Minerals: Vitamin C (scurvy), vitamin D (rickets), iron (anaemia), and calcium—with functions and deficiency diseases. BMI & Malnutrition: Body Mass Index calculation and interpretation, plus undernutrition (kwashiorkor, marasmus) and overnutrition (obesity, type 2 diabetes, CHD) consequences. Common Exam Errors—Side-by-Side Corrections: Six of the most frequent mistakes students make on human nutrition questions, with the correct answers examiners expect. This guide is perfect for: Students who need a clear, concise, no-fluff review of a high-priority syllabus chapter. Teachers looking for a ready-to-use content summary to support classroom teaching or revision sessions. Tutors who need a structured resource to help students master enzyme tables, villi adaptations, and diet-related diseases. Stop losing marks to vague explanations and common misconceptions. Get the precise language and clear frameworks you need to answer any human nutrition question with confidence.Format: PDF (Instant Download)
