Lesson Plan

• Describe the key structural features of elastic arteries, muscular arteries, capillaries, and veins.
• Explain how each vessel’s structure supports its specific physiological function.
• Compare the roles of different blood vessels in maintaining blood pressure and tissue exchange.
• Predict the impact of structural changes (e.g., atherosclerosis) on vessel function.
• Apply knowledge of vessel structure‑function to answer case‑study questions.

• Projector and screen
• PowerPoint presentation with vessel diagrams
• Handouts of the comparative summary table
• Microscopic images or models of blood‑vessel cross‑sections
• Whiteboard and markers
• Exit‑ticket slips

Begin with a short animation of blood being pumped through the circulatory system, asking students why some vessels feel “hard” while others are “soft”. Recall previous learning on the three layers of blood vessels and state today’s success criteria: identify structural features and link them to function for four vessel types.

1. Do‑now (5 '): Students label a blank diagram of a blood‑vessel wall.
2. Mini‑lecture (10 '): Present key structural features of elastic and muscular arteries using slides.
3. Interactive activity (12 '): In pairs, create a comparison chart of the four vessel types and justify each function.
4. Demonstration (8 '): Examine microscope images of capillaries and veins; discuss diffusion distance and valve function.
5. Guided practice (10 '): Answer short questions linking structure to function.
6. Quick check (5 '): Kahoot quiz to assess understanding.
7. Summary & exit ticket (5 '): Students write one structure‑function relationship and hand in an exit ticket.

Review the main points that connect vessel structure to its role in blood flow and exchange. Students complete an exit ticket summarising a structure‑function link and receive a homework task to research a circulatory disorder that illustrates these concepts.
