ORIGINAL: CalliopePurple Ragdoll - When blood is drawn from your arm or hand at a hospital, that is a vein. That's why they tell you to apply pressure and keep the bandage on for a bit afterwards. Fingersticks connect with capillaries and they are also the vessels that bleed in the case of most not too deep cuts or scrapes. In the case of the typical "cry for help" cut wrists that goes horizontally across the wrist, unless it's deep, no veins are cut. But in more serious attempts that run vertically, those are meant to hit the arteries and veins. And I haven't even started nursing school yet. Gods, I'm a nerd. the typical case of someone trying to "cry for help" or actually think they will slit their wrists to commit suicide results in no severed arteries, but instead severed median nerve and flexor (bending) tendons that control the fingers. the radial artery is actually on the side of the wrist (think of your thumb facing up and you've got it) while the ulnar artery is on the opposite side of the wrist and deep. it's often not even caught right in the ER as docs sew the remnants of the severed nerve to the flexor tendons. aside from that, cutting any artery, even the ones to the hands, will result in death in a relatively short amount of time if the bleeding is not stopped. if you've ever cut your finger on the side deeply, and it won't stop bleeding for hour(s) even with direct pressure and elevation, you've likely cut the nerve and artery, as the two tend to run alongside one another in the body. okay, enough med school preaching for the day. but cutting arteries, carotid, femoral, coronary, or radial is a quick route to the morgue. the only variance is time.
