Is Blood Blue?
Kristen addresses the argument over whether human blood is blue. She talks about common misconceptions and what gives blood its color. As a bonus, she also talks about the variations in colors of blood in other animals.   CORRECTION: In this episode, Kristen says “octopi” to indicate the plural of “octopus.” Because “octopus” originated from Greek and not Latin (which does use “i” to pluralize words) and because “octopus” has been a word in English for a long time, Kristen would have preferred to pluralize the word using English rules: “octopuses.” Correction references and other neat facts about octopuses: https://www.smithsonianmag.com/science-nature/ten-curious-facts-about-octopuses-7625828/ https://www.merriam-webster.com/words-at-play/the-many-plurals-of-octopus-octopi-octopuses-octopodes   Episode References and Resources Textbook: Vander’s Human Physiology 13th Edition Blog on why veins appear blue: https://scienceblogs.com/scientificactivist/2008/04/17/why-are-veins-blue Primary publication from 1996: https://pdfs.semanticscholar.org/22db/3b06a1abb585cb4c0683dd03a806800c1c28.pdf Animal Blood Comes in a Rainbow of Colors: https://news.nationalgeographic.com/2015/03/150312-blood-antarctica-octopus-animals-science-colors/   Connect - Leave comments, suggest topics, and ask science questions!
