This engaging lesson explores the structure and function of the mammalian heart and its role within the circulatory system. Students investigate how the heart pumps blood around the body, examine the advantages of double circulation, and compare the adaptations of arteries, veins and capillaries.

Learners develop their understanding of heart anatomy through labelling activities and practical model-building tasks, before applying their knowledge to trace the pathway of blood through the heart and circulatory system. The lesson combines theoretical content with creative and interactive activities, making complex cardiovascular concepts accessible and memorable.
