Viral infection of the blood vessels, vascular damage, and vasoconstriction B. Bacterial infection of the nervous system with widespread vasodilation C. Widespread vasoconstriction and plasma loss due to a severe viral infection D. Bacterial damage to the vessel wall, leaking blood vessels, and vasodilation - D Which of the following statements regarding anaphylactic shock is correct? Select one: A.
