Acutely poor delivery of oxygen to tissues such as due to pathologically low blood pressure.

Generally shock occurs when normal compensatory mechanisms ‐ as would normally result in homeostasis – give rise to compensatory mechanisms that instead have the effect of reducing the efficiency of blood circulation in a positive feedback manner.

More precisely, shock is referred to as circulatory shock. See also septic shock.

There are a number of causes of circulatory shock. Septic shock, for instance, is associated with systemic increases in arterial diameters (vasodilation) that has the effect of reducing blood volume as a function of blood vessel capacity, resulting in reduction in blood pressure.

The following video walks us through just what circulatory shock consists of as well as it cause and some symptoms:
