Diagram pack: Human Heart and Blood Flow
Stage 1/4: Outer shape
Vocabulary to include
- Right atrium
- Right ventricle
- Left atrium
- Left ventricle
- Aorta
- Vena cava
Drawing steps
- Sketch symmetrical outer heart shape.
- Add four chambers — mind left/right on the page vs body.
- Draw aorta arch and pulmonary vessels.
- Arrow blue deoxygenated and red oxygenated paths.
- Label valves at chamber exits.
Flow
- Body → RA → RV → lungs → LA → LV → aorta → body
Real-life application
- Why does your heart beat faster when you run?
- Where does oxygen-rich blood go after leaving the left ventricle?
Common mistakes to avoid
- Swapping left and right on paper
- Missing valves
- Arrows crossing without logic
Safety: Simplified educational diagram, not medical advice. Use with teacher guidance in class.
Drawing steps
- Sketch an outer heart outline.
- Divide into four chambers.
