Question

Quizplus · Accepted Answer

Inflammatory mediators, such as histamine and prostaglandins, are released during the vascular phase of inflammation and cause the blood vessels to dilate and become more permeable, allowing immune cells to migrate to the site of injury or infection. White blood corpuscles and blood platelets are important components involved in the immune response, but they do not directly cause vasodilation or increased vascular permeability. C-reactive proteins are acute phase proteins that are released in response to inflammation but do not play a direct role in the vascular phase.
