ok well i was in an event... and the question was what are the 4 heart valves, i answered them right and didnt get my prize which was supposed to be 20b, now i know my answered were right because my wife is a nurse and i have 3 medical books in front of me, i looked at them over and over after the event to make sure, and looked online to make sure and i was right... here is a website showing 4 heart valves, straight from american heart assoc.
