  2. The right atrium pumps the deoxygenated blood to the right ventricle.
  3. From the right ventricle, the deoxygenated blood moves to the lungs via the pulmonary artery.
  4. After gaseous exchange, the oxygenated blood returns to the heart into the left atrium via the pulmonary vein.
  5. From the left atrium, blood moves to the left ventricle.
  6. Oxygenated blood is pumped by the left ventricle into the aorta which supplies blood to all parts of the body.
  7. Deoxygenated blood, collected from the body again enters into the right atrium via the vana cava.

It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
