Cells at Work! Omnibus 1 (Vols. 1-3)

"Follow the 37 trillion cells inside a human body, including Red Blood Cell, White Blood Cell, Macrophage, and, of course, the cute, little Platelets, as they face off against threats like cedar pollen, parasites, food poisoning, staph infection, and their ultimate nemesis, cancer. Twenty-four hours a day, 365 days a year, these tiny workers are doing their best to keep you moving. This new omnibus edition brings the series back in a larger page size, with three volumes in one."--Publisher marketing.
