immune response - Answers is considered to be the third line of defense and wages a specific defense
depending on the type of invader
Injury - Answers is defined in the broadest sense to include any form of damage or alteration to cells or
tissues
vascular response - Answers to increase blood flow to the site of an injury
cellular response - Answers to alert the products of healing to attend to the site of injury
dilate - Answers widen
permeable - Answers loosening to allow cells to easily move through tissues or vessels
Endothelial cells - Answers form a tight junction within the inner lining of the blood and lymphatic
vessels and the heart
basement membrane - Answers is the outer membrane of the vessels, which separates the vessel from
the tissues of the body
phagocytosis the process of engulfing and removing harmful agents, as well as cells essential in
promoting healing and developing an immune response. - Answers
Exudate - Answers the watery fluid that accumulates at the site of injury, has a high protein and
leukocyte concentration
Inflammatory mediators - Answers specifically vasoactive inflammatory mediators, facilitate the process
of widening and loosening the blood vessels at the site of injury.
Mast cells - Answers are leukocytes (WBCs) that are housed throughout the connective tissues of the
body and near all blood vessels. allows for a rapid response directly at the site of the injury
degranulation - Answers the mast cell breaks apart and releases inflammatory mediators in the form of
extracellular granules
basophil - Answers a WBC that also contains granules, functions in the same manner.
cytokines - Answers are more than a hundred distinct cell proteins most often found within WBCs that
have a vital role in regulating inflammation; they are active from the onset of vasodilation and increased
vascular permeability to the resolution of the inflammatory response (cytokines released from
lymphocytes are called lymphokines; monocytes or macrophages are called monokines)
Platelet-activating factor - Answers is a potent inflammatory mediator that has a key role in promoting
vessel vasodilation, clotting, and attracting infection-fighting WBCs to the site of injury
