Blood is something we all know exists from infancy on, but few of us really examine that which carries oxygen to our various body parts and keeps us alive. Whether it is our inability to fully understand the intricacies of the substance flowing through our veins and arteries, or our collective squeamishness at the sight of it, blood remains largely a mystery to the masses. In The Book of Blood: from Legends to Leeches to Vampires and Veins, author HP Newquist examines this mystical fluid, our literal lifeblood.
Many hematological topics are covered and well-explained, such as the various blood cells, the makeup of plasma, and diseases involving blood, such as leukemia and hemophilia. Illustrated using digital imagery, photography and reproductions of blood-related ephemera, The Book of Blood could go for the jugular in terms of gore and unpleasantness, but instead uses appropriate restraint in portraying the substance. The various bloods of animals are discussed, too, whether it be the differences between warm- and cold-blooded beings, or those animals that have blood in colors other than red, such as blue blood of many mollusks.
Titles such as this, covering one commonly known subject, give readers the ability to focus on a topic and better understand the ways blood works and how it is an unspoken part of everyone’s life. The cultural meanings of blood are also touched upon, with references to mosquitoes, leeches, and bats, and of course, vampires. The book closes with a chapter that reminds us of the long way we still have to go in medicine. Blood donations remain critical because, despite so many other medical advances, we have not yet been able to create blood in a laboratory.
