The heart has only two ventricles, not three as previously believed. The septum is solid and does not permit blood passage.

Blood flows from the right ventricle to the lungs, where it is mixed with air, and then returns to the left ventricle.

The pulmonary circulation is the true path of blood, not the imaginary pores in the septum.

Observation and deduction are the cornerstones of true knowledge, not blind adherence to ancient texts.

To understand the body, one must first understand the flow of its vital fluids.

The lungs are not merely for cooling the blood, but for its vital transformation.
