Hypo-volemic shock, a sudden loss of a large volume of blood,can cause arterial blood pressure to drop significantly, which cancompromise blood flow. However, if the loss of blood is not toogreat, say less than 20% or so, the circulatory system usuallyresponds almost immediately in two ways to restore adequate bloodflow. Based upon your understanding of the circulatory system, andcontrol of blood pressure explain what quick cardiovascularadjustments are made to restore flow. Be sure to explain how eachadjustment works
