Vascular, due to extreme vasodilation as a result of loss of vasomotor tone
Circulatory shock, or simply 'shock' is a life-threatening medical condition. One is in shock when blood isn't sufficient to supply the brain with oxygen. The shock is progressive and it can be deadly if it is not made well quickly.

Closed Circulatory system
Think of the circulatory system as a tank with a pump and pipes. The tank is the human body, the pump is the heart, and the vessels are the pipes. You can have pump failure that causes shock - the pump just doesn't work well. Cardiogenic Shock. You can have a break in the pipe - you lose volume. Hypovolemic shock. You can have the pipes get bigger, wider. Neurological shock. You can also have a psychogenic type shock. Nothing is wrong with the pump, pipes, or volume but you see something your mind just can't handle and you faint. Neurological shock is normally an anaphalactic type response. Isolated head trauma rarely causes shock.
