Question

Quizplus · Accepted Answer

Endothelial cells release mediators such as cytokines and chemokines in response to an infection to contain the spread of the infection. This process is responsible for the improvement seen in the patient's wound. Choice A is incorrect as cortisol is involved in the stress response and not specifically in the immune response to an infection. Choice B is incorrect as the hypothalamus is not directly involved in activating white blood cells. Choice D is incorrect as mediators that decrease vessel wall permeability may actually worsen the infection by preventing immune cells from reaching the site of infection.
