What to do if you hit a vein while cutting?

First of all, arterial and venous blood flows are different. Arteries spurt from the blood pressure used to propel the blood away from the heart, but veins let the blood flow. If you know the pressure points (behind the elbows, carotids at the neck, near the underarms, on the wrist, and on the inside of knees), then press between the wound and the pressure point before that point in the blood's journey through the blood vessels. THANKS DUDE. YOU DID MY HOMEWORK FOR ME!!!!!!
