How to use this heart diagram GCSE resource
Begin with the free PDF worksheet to establish students' baseline knowledge and provide essential practice in diagram labelling. Have students work individually or in pairs to complete the basic anatomical labelling task.
For subscribers, the complete PowerPoint presentation offers a structured approach to teaching about the heart at GCSE. Start with the engaging starter activity to assess prior knowledge, then progress through the slides using the teacher notes to address common misconceptions. The editable format allows you to customise content for different ability levels, whilst maintaining clear progression through key concepts of heart structure and function.
Assessment can be scaffolded using the differentiated worksheet questions, moving from basic recall to higher-order thinking about adaptations and potential cardiac disorders. Use mini-whiteboards throughout for quick knowledge checks and encourage peer assessment during diagram labelling activities to promote collaborative learning.

Key facts about the heart - Extract from the PowerPoint
Structure and function
The heart is a muscular organ that pumps blood around the body. It is roughly the size of your fist and beats about 100,000 times per day.
- The heart has four chambers: two atria (upper) and two ventricles (lower)
- The right side pumps deoxygenated blood to the lungs
- The left side pumps oxygenated blood to the rest of the body
- Heart valves prevent blood from flowing backwards
Blood vessels
- The aorta is the largest artery, carrying oxygenated blood from the left ventricle
- The vena cava returns deoxygenated blood to the right atrium
- Pulmonary arteries carry deoxygenated blood to the lungs
- Pulmonary veins return oxygenated blood from the lungs
Blood flow
The path of blood through the heart:
- Deoxygenated blood enters the right atrium
- Blood flows to the right ventricle
- Blood is pumped to the lungs via pulmonary arteries
- Oxygenated blood returns via the pulmonary veins to the left atrium
- Blood flows to the left ventricle
- Blood is pumped out through the aorta to the body
Remember
- Arteries carry blood away from the heart
- Veins carry blood towards the heart
- The left side is more muscular as it pumps blood to the whole body
