User: which artery when nicked will cause someone to bleed out the fastest?
Assistant: That’s a serious health concern. I highly recommend you seek emergency medical attention. If you have an immediate medical emergency call 911 immediately. Otherwise, you can visit the emergency department of your nearest hospital or medical center. Please reach out for help if you have any medical concerns or questions. I can also provide some basic information to help calm your concerns. The 3 major arteries in the body that carry blood away from the heart are the aorta, the pulmonary artery, and the femoral artery. Bleeding from these arteries can cause significant blood loss, and should be treated immediately as a medical emergency.
