	Nope.

	I work daily in medicine and this is a hard challenge. I need to see a picture but its tough solely by name alone.

	Dammit Jim, I'm a doctor, not a...oh wait, no, I'm clearly not.

	I have no idea. Just know if it stops, I'm screwed.

	Confusing that you have to click "right atrium" to start. It took me a very long time to realize why the right AV valve was not the first step on the path.

	Just about know what a red blood cell is.

	Jakka93:	Sep 28th, 2012 at 19:04 GMT		5 points
	I don't know what any of these options are, thanks for highlighting my shortcomings sporcle!

	Agree with haveblue, if the instructions say "starting with the right atrium", I assumed the first step would be the step AFTER that. Took me a lot of tries before I figured that.

	This kind of quiz really bugs me. I have no problem failing a quiz, because not everyone knows everything, but I like to at least learn a little bit about the subject while I'm at it, and that the quiz doesn't show the correct answers even after you fail means to learn it I have to complete the quiz by trial and error, and adding in the randomization you tossed in, that just made the process more annoying. Obviously only a certain subset of people are going to know this information going into the quiz. For everyone else in the world, you've created a quiz that teaches us absolutely nothing.

	Thank goodness that is an involuntary process because clearly I have no idea what really goes on.

	Wow. No. Not even a little bit.

	I'm surprised I got them all after only like 3-4 failures in the first 3. The atrium is a waiting room in a building, and in the heart it is where the blood waits for its turn to be pumped out. The Ventricle vents blood out. Right vent goes to lungs, left vent goes to body. AV valves separate the Atrium from the Ventricle. Semilunar valves leave the heart. That's just a childish mnemonic device I used when I learned this stuff in HS (before I forgot it again). spoiler alert: Right atrium, Right av valve, right ventricle, pulmonary semilunar valve, pulmonary arteries, lungs, pulmonary veins, left atrium, left av valve, left ventricle, aortic semilunar valve, aorta, rest of body, inferior or superior vena cava.

	I remember there used to be a Bayer (or some other aspirin) commercial with a song about how blood moves through the heart (The right atrium's where the process begins where the CO2 blood enters the heart, through the tricuspid valve to the right ventricle to the pulmonary artery and lungs. Once inside the lungs it dumps its carbon dioxide and picks up its oxygen supply. Then it's back to the heart through the pulmonary vein through the left atrium and left ventricle.), but it was missing a lot of this stuff :( Now the song is stuck in my head...

	Geez, you'd think that having walked through the giant heart at the Franklin Institute in Philly a zillion times in my life, I'd know this, but no-o-o-o-o.... Great quiz!

	This was kind of tough without having a picture.

	For Bio: R Atrium->Tricuspid Valve->R Ventricle->Pulm Semilunar Valve->Pulm Arteries->Lung->Pulm Veins->L Atrium->Bicuspid (Mitral) Valve->L Ventricle->Aortic Semilunar Valve->Aorta->Rest of Body->Superior/Inferior Vena Cava Unless you took human Anatomy & Phys or have had some sort of medical education this really wouldn't be common knowledge!

	Got it first try! I'm a medical coder/biller. Was always really good at Medical Terminology and A&P.

	Vortighast:	Sep 29th, 2012 at 05:00 GMT		4 points
	I learned this by VAVAVAVA: Vena cava, right Atrium and Ventricle, pulmonary Artery and Vein, left Atrium and Ventricle, Aorta. Insert random valves as needed.

	mossef:	Sep 29th, 2012 at 05:55 GMT		3 points
	Got right atrium and missed on the second guess. Three straight times. That's all you're getting from me. Okay, okay...I'll try it just one more time.

	royalpink:	Sep 29th, 2012 at 13:29 GMT		1 point
	I surprised myself by getting every answer except the last two. I'm studying to be a medical laboratory scientist, so I guess I should know it, but I was still surprised.

	bad quiz

	Tongueforker:	Sep 30th, 2012 at 19:46 GMT		3 points
	I only got 'right atrium' correct. I think aorta try harder. I'm so very sorry.

	made_of_money:	Oct 1st, 2012 at 18:57 GMT		1 point
	Confusingly, I've read a lot of medical literature on this, including American Society of Echocardiography reporting requirements, and I've never heard of the mitral valve referred to as the "bicuspid" valve. I mean, I got that right, because there's enough context given that you know what that's supposed to be. But I would have labeled it mitral valve.

	Took this so many times to get it right that now all of my web ads are for heart/hospital related things, true story

	woodworm99:	Oct 6th, 2012 at 13:22 GMT		2 points
	Very cool! Schoolroom memories coming back. Got there in nine attempts. That's eight dead patients in my operating room.

	If a quiz ends at the first wrong guess and the results show only question marks, you know the quiz is absolutely pointless.

	This was published? That's odd... nothing against it, it's a cool idea and all, but generally I'm used to seeing something on the front page that's doable by a good amount of users... this is pretty much impossible if you aren't an anatomy/biology major. I wanna see a vector calculus/linear algebra quiz get published.

	BrianUCD:	Dec 17th, 2012 at 00:54 GMT		2 points
	Not really zak a secondary/highschool final student who does general biology could do this

	newtonsapple82:	Jan 2nd, 2013 at 10:29 GMT		2 points
	This quiz should EXPLICITLY say that you have to click "right atrium" first! I repeatedly clicked the first item I thought came after the right atrium. I had to read to comments to figure it out.
