Inflammation

Question 1

What needs to happen for the inflammatory response to happen?

Answer 1

Vascular response ( increased blood flow to the site of injury), cellular response (alert healing products to come to the site of injury), and removing the injured tissue to prepare for healing

Question 2

Why is the inflammatory response so important in healing?

Answer 2

Getting blood to the site of injury allows cells that participate in phagocytosis to come to the area. It also allows platelets to come to the area and clot

Question 3

Cellular inflammatory mediators

Answer 3

White blood cells, platelets, and endothelial tissues

Question 4

Inflammatory mediators in plasma

Answer 4

Kinin system, complement system, clotting system

Question 5

Cellular response

Answer 5

Involves chemotaxis, cellular adherence, and cellular migration

Question 6

Local signs of inflammation

Answer 6

Redness, heat, incapacitation, edema, and pain

Question 7

Acute vs chronic inflammation

Answer 7

Acute: resolves within a few weeks, Neutrophils are the chief cells, and results in minimal scarring
Chronic: lasts more than 6 months, chief cells are Lymphocytes, Monocytes, and Macrophages, and usually results in some scarring

Question 8

Three phases of wound healing

Answer 8

Inflammatory (seals the wound), proliferative (cleans the debris and restores structural integrity), Remodeling (structural integrity and remodeling)
