Characteristics of Inflammatory Response

Question 1

immediately upon the occurrence of an insult to a site, the blood vessels in that area constrict and then dilate, allowing blood to pool in the area as the vessels fill and blood is unable to flow quickly through the undilated vessels beyond the injured areas.

Answer 1

rubor

Question 2

the inflammatory exudate, especially the chemicals released by the injured cells, result in pain. The pain may help to protect the site by telling the organism to give it attention and to be careful with it.

Answer 2

pain

Question 3

as white blood cells, chemicals, fluids that leak from damaged blood vessels and cells, and other inflammatory exudate enter the interstitial areas, the injury site begins to bulge. Certain proteins in the interstitial solution transform into fibrin to form clots that seal the area. This helps to isolate the site so that pathogens are contained and infection is more easily prevented. This accumulation of body fluid is referred to as edema.

Answer 3

swelling

Question 4

white blood cells begin to accumulate in the injury site, attaching to the blood vessel walls and leading the body to release stored white blood cells. The white blood cells begin to pass through the walls of the blood vessels to fill the interstitial spaces attracted by chemicals such as kinins released by the injured tissues. The purpose of the white blood cells is to attack pathogens that may have entered a wound. They also fill the area with concentrated warmth.

Answer 4

heat
