Let's go on a "Fantastic Voyage". Imagine that you are a video reporter piloting a mini-sub that has been put through a miniaturization process making you and the sub only 8 micro long(Ever see the movie "Inner Space"?) You have been injected into the femoral vein of a healthy female. The alert just came out that a bacterium is invading the lower lobe of right lung. Trace your path from the right femoral vein via the lower lobe of the right lung via the right pulmonary artery. Rules of the road: A. You may never go the wrong way down a "one-way street". B. You are allowed to "create" new roads. C. You may choose any possible route.
