The Four Heart Chambers
Captions available
The idea
The heart has four chambers: a right and left atrium above, and a right and left ventricle below.
In practice
Blood enters an atrium and is pumped out by the ventricle beneath it.
Where people slip
Right and left are the patient's, so on an image the right side appears on the left.
