In brief: The heart works like a double pump: the right side sends blood to the lungs and the left side sends it to the body.
The route step by step
| Station | Role |
|---|---|
| Right atrium | Receives oxygen-poor blood |
| Right ventricle | Pumps to the lungs |

| Left ventricle | Pumps to the body |
Why valves matter
Four heart valves help keep blood moving mainly in one direction.
