Q. Trace your path from the right femoral vein to the lowest lobe of the right lung via the right pulmonary artery.
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)
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 grinded in the first 4 units. Address both specific and nonspecific immunity and the cells that are involved in each process
Once you have documented the "battle of the Lung" cross the alveolar membrane, and trace your route out of the body through the nose.
