Question

Vasodilation promoted by the release of vasoactive factors from macrophages leads to

A. stimulation of local nerve endings, causing pain
B. decrease of fluid accumulation at the site
C. loss of heat to the affected area
D. decrease of blood flow to the affected area

Answer 1

Vasodilation, promoted by the release of vasoactive factors from macrophages, leads to increased blood flow to the affected area, resulting in apparent redness and heat.

Step-by-step explanation:

Vasodilation, which is the widening of blood vessels, is promoted by the release of vasoactive factors from macrophages. This leads to increased blood flow to the affected area, resulting in apparent redness and heat.

Increased blood flow also allows for greater access of white blood cells to the site of inflammation. However, vasodilation does not cause a decrease in blood flow to the affected area. Instead, it promotes increased blood flow for various physiological responses.
