AI Expt. - Blood Flow Through the Heart

Explore how blood travels through the four chambers of the heart. Use the teacher's controls to pause, step through the circulation, or highlight oxygenated and deoxygenated blood.

Important: This is a simplified teaching diagram, not a physiological simulation. Blue represents oxygen-poor blood, not its literal color. Pulmonary and aortic valves and the lungs are described but not individually illustrated. The heart is shown in anatomical orientation (the right heart is on the viewer's left). On narrow screens, scroll the diagram horizontally to read every label.

Teacher's control & explanation

Choose a stage, then pause the animation to explain the structure. The text below updates as you navigate the circulation.

Body → Vena cava → Right atrium → Tricuspid valve → Right ventricle → Pulmonary artery → Lungs
Lungs → Pulmonary veins → Left atrium → Mitral valve → Left ventricle → Aorta → Body

Teacher's lesson script

Suggested narration for the current stage. Select and copy it into your AI tutor, or adapt it for classroom teaching.

Teaching suggestion: Ask the student why the pulmonary artery is shown in blue even though it is an artery. The answer: arteries carry blood away from the heart; they do not always carry oxygen-rich blood.
