The experiments start with a dog's heart, attached to a set of tubes to serve as substitutes for the great vessels. Using a system to supply it with blood, the heart beats in the same manner as if it were inside a living organism. The film then shows a lung in a tray, which is operated by bellows that oxygenate the blood being sent to the heart ...

[93] Galen believed the arterial blood was created by venous blood passing from the left ventricle to the right through 'pores' between the ventricles. [90]
It all takes place inside a computer, where the test can be replicated across thousands of other hearts - all AI-simulated versions of a real human heart. Human and animal trials, on the other ...
