Now on ScienceBlogs: A study that oversells massage therapy
You will notice that it lacks definiteness; that it lacks purpose; that it lacks coherence; that it lacks a subject to talk about; that it is loose and wabbly; that it wanders around; that it loses itself early and does not find itself any more. --Mark Twain

This t-shirt, despite the various forms of awesomeness Preshrunk describes, is unacceptable.
It shows blood moving out from the atria. The pulmonary artery is flowing into the heart (and possibly also out from it!). Blood is shown going backwards into the aorta! This sort of biological inaccuracy should not grace anyone's chest.

Is it deliberately bass-ackwards? Some sort of in-joke? Because it's almost entirely wrong. Randomly sticking arrows on a heart should give you a better outcome than that!
If I was teaching A&P this year, I'd put it on a quiz and ask the students to redraw it properly. . .

I'm fascinated by the blood moving both directions through the pulmonary artery.
If this is intentional, I don't know why.

I want a t-shirt with one of those cross section hearts, exactly the right size and location, and diagrams that are accurate. In realistic blood red. Get to it...

But go look at the shirt on the website. The title of it is "arrhythmia". The term arrhythmia refers to any change from the normal sequence of electrical impulses, causing abnormal heart rhythms. So, not only is the blood flow wrong, the title is misleading. Although, chances are if your blood is flowing that way, you will have an arrhythmia. But heck, it's a t-shirt!

Also it shows the heart as black, which whould only be accurate if worn by Nancy Pelosi.
