Something near and dear to my heart (and neck)

This is an article with case studies focusing on the anatomy of a choke. In judo we learn when we want to subdue an opponent by a choke, we must cut off circulation to the brain by constricting the carotid arteries. After a short period of time the blood becomes low in oxygen and the victim passes out. The article shows what the other physical effects of a choke are.
