What you'll learn
In this course students will learn exactly what they need to know for their Biology IGCSE exams. Students will learn about[/center]
1. Describe what is meant by a balanced diet
2. State the principal dietary sources and describe the importance of
(a) carbohydrates
(b) fats and oils
© proteins
(d) vitamins, limited to C and D
(e) mineral ions, limited to calcium and iron
f) fibre (roughage)
g) water
3. State the causes of scurvy and rickets
4. Identify in diagrams and images the main organs of the digestive system, limited to
(a) alimentary canal: mouth, oesophagus, stomach, small intestine (duodenum and ileum) and large intestine (colon, rectum, anus)
(b) associated organs: salivary glands, pancreas, liver and gall bladder
5. Describe the functions of the organs of the digestive system listed in 7.2.1, in relation to
(a) ingestion - the taking of substances, e.g. food and drink, into the body
(b) digestion - the breakdown of food
© absorption - the movement of nutrients from the intestines into the blood
(d) assimilation - uptake and use of nutrients by cells
(e) egestion - the removal of undigested food from the body as faeces
6. Describe physical digestion as the breakdown of food into smaller pieces without chemical change to the food molecules
7. State that physical digestion increases the surface area of food for the action of enzymes in chemical digestion
8. Identify in diagrams and images the types of human teeth: incisors, canines, premolars and molars
9. Describe the structure of human teeth, limited to: enamel, dentine, pulp, nerves, blood vessels and cement
10. Describe the functions of the types of human teeth in physical digestion of food
11. Describe the function of the stomach in physical digestion
12. Outline the role of bile in emulsifying fats and oils to increase the surface area for chemical digestion
13. Describe chemical digestion as the breakdown of large insoluble molecules into small soluble molecules
14. State the role of chemical digestion in producing small soluble molecules that can be absorbed
15. Describe the functions of enzymes as follows
(a) amylase breaks down starch to simple reducing sugars
(b) proteases break down protein to amino acids
© lipase breaks down fats and oils to fatty acids and glycerol
16. State where, in the digestive system, amylase, protease and lipase are secreted and where they act
17. Describe the functions of hydrochloric acid in gastric juice, limited to killing harmful microorganisms in food and providing an acidic pH
18. Describe the digestion of starch in the digestive system
(a) amylase breaks down starch to maltose
(b) maltase breaks down maltose to glucose on the membranes of the epithelium lining the small intestine
19. Describe the digestion of protein by proteases in the digestive system
(a) pepsin breaks down protein in the acidic conditions of the stomach
b) trypsin breaks down protein in the alkaline conditions of the small intestine
20. Explain that bile is an alkaline mixture that neutralises the acidic mixture of food and gastric juices entering the duodenum from the stomach
21. State that the small intestine is the region where nutrients are absorbed
22. State that most water is absorbed from the small intestine but that some is also absorbed from the colon
23. Explain the significance of villi and microvilli in increasing the internal surface area of the small intestine
24. Describe the structure of a villus
25. Describe the roles of capillaries and lacteals in villi
Requirements
Access to a device to watch lessons - phone, tablet, or computer No textbook needed - everything is covered in the course
Description
This Biology course is structured specifically around the latest Cambridge IGCSE and GCE Biology syllabus, ensuring complete and accurate coverage of every objective students need to master for their examinations. Students preparing for AP Biology, IB Biology, or equivalent international curricula will also find this course highly valuable for building a thorough understanding of the theory component of their exams, as the core biological concepts covered are closely aligned across these specifications.
The course focuses onUnit 7: Human Nutrition, one of the longest and most detailed units in the entire Biology course - and one of the highest-scoring opportunities in the exam for students who are properly prepared. Every syllabus objective is covered in full across Papers 1, 2, 3 and 4, with zero gaps.
Every syllabus objective is covered comprehensively, without overloading you with irrelevant material. The content is precise, focused, and directly aligned with what examiners expect - so you spend your time learning exactly what matters and nothing that does not. Throughout every lesson, real past paper questions are used to show you how this unit is examined, what a full-mark answer looks like, and the common mistakes that cost students marks every single year. You will know not just what to say, but how to say it - and equally importantly, what not to write.
The course builds strongexam technique alongside content knowledge, covering every question type across Papers 1, 2, 3 and 4 - from multiple choice and short answer to structured and extended response questions. Students leave this course knowing exactly how to approach any question on this unit regardless of how it is worded.
Every video lesson comes with adownloadable PDF resource that contains everything you need to know for that specific lesson - definitions, diagrams, key points and exam tips - all written and structured to match exactly what the syllabus requires. There is no need to open a textbook, search for revision guides, or look anything up online. Simply watch the lesson, download the PDF, study from it, and go straight to past papers. Everything you need is right here in one place.
This unit is entirely theory-based - there are no practical experiments associated with it. This means every minute of the course is focused purely on building the depth of knowledge, precise scientific language and exam technique needed to score full marks across all theory papers. Particular attention is given to the areas students find most challenging, including enzyme specificity in digestion, the distinction between physical and chemical digestion, the roles of bile, and the detailed structure and function of the small intestine at supplement level.
This course is ideal for students aiming for high achievement and A* grades in Biology examinations.
