Question

1.In a famous science fiction movie, a group of scientists in a submarine are miniaturized and injected into a patient's bloodstream. Their mission is to travel to the patient's brain and remove a blood clot that has caused the patient to become comatose.
During their journey to the brain, the shrunken scientists encounter many of the structures discussed in this lesson and have some dangerous encounters with them. They have to move quickly to avoid being attacked by the patient's immune system, which recognizes them as foreign objects.

For this discussion, imagine yourself as one of these scientists. Respond to the following questions from the viewpoint of traveling through a patient's bloodstream in a miniaturized submarine.

Answer 1

I would start by stating that it's the white blood cells that are trying to fight you.  Mention phagocytosis.  And describe what it looks like.  Basically this is just asking for you to explain how the immune system works within the body. You can PM for a good site to use as a source if you don't know how this works within the body.
