IB Biology B3.2.2 Artery & vein structure
Practise comparing arteries and veins from diagrams or descriptions, using lumen size, wall thickness, elastic tissue and valves as evidence.
How this is tested
- distinguish arteries from veins by comparing wall thickness, lumen size and valves
- identify an artery or vein in a micrograph and justify the choice using structure
- explain how artery and vein structures match high-pressure and low-pressure flow
