* The external carotid artery
This is the most common place of all to have a vampire bite. This is the artery in the side of your neck where you take your pulse, closest to the surface between the jaw, slightly under the earlobe and forward, and the collarbone.
* The jugular vein
Extending on either side of the trachea (the throat), following down the neck from the chin to the collarbone, this vein is very dangerous to pierce. The jugular leads directly down into the heart and carries all the blood from the brain. The jugular vein is much larger than the carotid artery, and so carries much more blood.
* The median cubital vein
This vein is the one in the elbow where, if you’ve ever had blood drawn, that is where they stick you.
* The ulner artery
This is the artery in the wrist. After the neck it seems to be the second favorite place for vampires to bite. Remember this though, the vein lies under some tendons (unlike the medial cubital which is right under the skin in the elbow), so that could pose a problem with biting.
* The greater saphenous vein
This vein runs along the inside of either thigh. The vein is large and deep; it would take a big bite to get down into it, but its location makes it a nice.
* The femoral vein
This vein is the one at the back of the knee. Like the median cubital in the elbow, this vein lies close to the skin and is an easy bite if you have a victim face down and willing to not kick or unable to kick.
