immune-response

In this chapter, the miniaturized crew navigates the lymphatic system, encountering lymph nodes and witnessing the immune response at a microscopic level. They observe the structure and function of lymphatic vessels, lymphocytes, and antibodies as these proteins target bacteria, illustrating the body's defense mechanisms. The chapter emphasizes the dangers and challenges of traveling through the lymphatic system, including the physical obstacles and immune reactions they must carefully negotiate.

In this chapter, the miniaturized crew aboard the Proteus confronts a massive white blood cell that has engulfed their ship, forcing Grant to attempt a risky maneuver to attract and lead the cell away. The team navigates through the optic nerve and lachrymal duct to escape the body, ultimately emerging safely on the surface of the eye just before de-miniaturization completes. The chapter concludes with the crew recovering and reflecting on the mission's success and the ambiguous character of Michaels.
