When the doctor/nurse takes blood from you, why do they try to find a vein, not an artery? And also why is this mainly done on the arm as opposed to other parts of the body?
In: Biology
My veins can tell when I walk into a lab. “Dive, Dive, Dive” — they head for the deeps. Last time I gave blood, it took three different people to get me going. They were almost ready to give up. Once, I had blood taken from the back of my hand — no sweat. Quick, easy, low pain. Don’t know why they don’t do it more often — professional pride?
