Blood flow through the heart
The heart is two pumps side by side. The right side sends oxygen-poor blood to the lungs; the left side sends oxygen-rich blood to the whole body. Valves between the chambers keep the blood moving one way.
Heart Flow has you put each journey in the right order, chamber by chamber and valve by valve, with a labelled diagram on every card. It also covers the heart's electrical system.
A taste of what's inside
| Journey | Order |
|---|---|
| Oxygen-poor blood: from the body to the lungs | Venae cavae → Right atrium → Tricuspid valve → Right ventricle → Pulmonary valve → Pulmonary artery → Lungs |
| Oxygen-rich blood: from the lungs to the body | Lungs → Pulmonary veins → Left atrium → Mitral valve → Left ventricle → Aortic valve → Aorta → Body |
