Lesson Plan
Grade: Date: 25/02/2026
Subject: Biology
Lesson Topic: describe the functions of the main blood vessels of the pulmonary and systemic circulations, limited to pulmonary artery, pulmonary vein, aorta and vena cava
Learning Objective/s:
  • Describe the direction of blood flow in the pulmonary artery, pulmonary vein, aorta, and vena cava.
  • Explain the oxygen content of blood carried by each vessel and its physiological significance.
  • Compare the structural adaptations of these vessels that support their functions.
  • Apply knowledge to label a diagram of the circulatory system accurately.
Materials Needed:
  • Projector and screen
  • PowerPoint slides with vessel diagrams
  • Handout containing summary table and blank diagram for labeling
  • Colored markers or pens
  • Interactive quiz platform (e.g., Kahoot)
 Introduction:
Begin with a quick poll: Which blood vessel do you think carries oxygen‑rich blood? Recall that arteries usually transport blood away from the heart and veins toward it. Today you will be able to identify and describe the four key vessels linking the pulmonary and systemic circuits.
Lesson Structure:
  1. Do‑now (5') – students answer the poll on the board and discuss any misconceptions.
  2. Direct instruction (10') – teacher presents slides covering each vessel’s direction, oxygen content, and primary function.
  3. Guided practice (10') – pairs complete the summary table on handouts while the teacher circulates.
  4. Diagram labeling activity (10') – learners use colored markers to label a schematic of the heart and the four vessels.
  5. Formative check (5') – quick Kahoot quiz on vessel functions.
  6. Recap (5') – class summary of key points and clarification of any remaining doubts.
Conclusion:
To wrap up, we revisited how each vessel contributes to oxygen transport in the body. For the exit ticket, write one sentence describing why the pulmonary artery is unique among arteries. Homework: complete the worksheet that asks you to compare the elastic properties of the aorta and vena cava.
