Actually Constrictors kill by causing Cardiac Arrest in the victim, by causing the veins and arteries in the blood system to become to shallow for blood to flow, thus causing the heart to stop.

This was shown the other night on a discovery documentary where they injected Xray dye into the man's arm and showed it without the snake, then did the same with a small 6ft bci constricting the arm and the blood flow was down to only the main artery in the man's arm.. none of the smaller vessels showed in the ray.
