Which of the following is a step that occurs within an inflammatory response?

a. local blood vessels near the wound close.
b. white blood cells leave these tissues allowing the pathogen to thrive.
c. fluid leaves the capillaries and causes swelling.
d. histamines decrease blood flow to the wound.

The right answer is C.

During inflammation, under the influence of chemical mediators, endothelial cells (forming the blood vessels) become activated. This leads to local arteriolar vasodilation then capillary2 which causes:

** an increase in blood supply

** a decrease in the speed of blood flow

This local swelling of the blood vessels causes redness and the sensation of heat. It aims to increase the flow of blood to evacuate dead cells and toxins (detox) and provide the elements necessary for healing, including white blood cells to fight against foreign bodies.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
