• Clear explanation of atheroma and narrowing of arteries
• Risk factors for cardiovascular disease (diet, smoking, cholesterol, exercise etc.)
• Understanding questions to check learning
• Do Now starter task
• Teacher answer sheet (reduced spacing for easy marking)

Perfect for:
• GCSE Biology lessons
• Retrieval practice / starter activities
• Homework or revision
• Cover lessons
• Exam preparation

Topics covered
• Capillary structure and function
• Diffusion between blood and tissues
• Atheroma and narrowing of arteries
• Cardiovascular disease risk factors
• Effects such as angina, heart attack and stroke

Suitable for KS4 GCSE Biology / Combined Science.
