1. Trace your path from the right femoral vein to 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 not allowed to “create” new roads
C. You may choose any possible route
Describe all major structures you pass by or through, just like a tour

guide would do (but you don’t need to indicate every “side road”).
2. Now that you’ve arrived at the lung, describe the structures you see,

and narrate how the body combats the invading bacterium using the knowledge

you have gained in the first 4 units. Address both specific and nonspecific

immunity and the cells that are involved in each process.
3. Once you have documented the “Battle of the Lung,” cross the alveolar

membrane, and trace your route out of the body through the nose.
