Quizplus · Accepted Answer

The increase in vascular permeability leads to fluid leaking out of the vessels and into the tissue, causing edema. In cases of anaphylaxis, the fluid leaves the vessels so rapidly that it can cause hypovolemic shock and death. While smooth muscle contraction may occur in allergic reactions, such as asthma, it does not always occur, and is not related to an increase in vascular permeability.
