Thanks to the University of Minnesota for sponsoring this video! http://twin-cities.umn.edu/ The same enzyme that used to save us is now killing us because the body reactions it catalyzes now cause more harm than good. Thanks also to our Patreon patrons https://www.patreon.com/MinuteEarth and our YouTube members. ___________________________________________ To learn more, start your googling with these keywords:  Cyclooxygenase: An enzyme responsible for the production of thromboxane and prostaglandins.Thromboxane: A lipid that acts as a platelet aggregator.Platelets: Special non-nucleic blood cells that clump together to cause blood clots.Prostaglandins: A lipid that causes vasodilation and inflammation.Aspirin: A form of acetylsalicylic acid that acts as an NSAID.NSAIDs: Non-steroidal Anti-Inflammatory Drugs that inhibit COX, and thus inflammation and clotting. ___________________________________________ Subscribe to MinuteEarth on YouTube: Support us on Patreon: And visit our website: https://www.minuteearth.com/ Say hello on Facebook: http://goo.gl/FpAvo6 And Twitter: http://goo.gl/Y1aWVC And download our videos on itunes:  https://goo.gl/sfwS6n ___________________________________________ Credits: Script Writer and Narrator: David Goldenberg Video Illustrators: Ever Salazar and Sarah Berman Video Directors: David Goldenberg and Ever Salazar With Contributions From: Henry Reich, Alex Reich, Kate Yoshida, Ever Salazar, Peter Reich and Julián Gómez Music by: Nathaniel Schroeder: ___________________________________________ References: Fitzpatrick, F.
