The blood seen, when flushing an aorta, while doing aortic replacement graft, is BRIGHT RED (oxygenated). Just like the bright red blood seen on the concrete. Blood drawn for arterial gasses is also bright red. Venous blood (de-oxygenated) is very dark and little redness seen, by me. But, being red-green colorblind, the arterial blood is, still, visible to me as red! Venous blood looks brown, to me.
I did 21 years of general surgery. I, also taught, as a lab assistant, in gross anatomy lab, (of the medical school that I attended) during my graduate school. Any claim that this did not look real, is absolutely ridiculous!
