Both false

During the Initiation Phase of acute inflammation changes begin in the small blood vessels. During the Amplification Phase chemical substances kick into action. true, false false, true both true both false

Both true

Fibrous repair is the final outcome when regeneration is not possible. A Keloid results from excessive scar formation. true, false false, true both true both false

Both true

When chemical mediators released by injured cells and bacteria drive leukocytes (PMNs) toward the area of injury it is called: Vasoconstriction Margination Phagocytosis Chemotaxis

Chemotaxis

All of the following are actions caused by histamine EXCEPT one. Which one is the EXCEPTION? -Constricts blood vessels -Dilates blood vessels -increases nasal mucous -increases vascular permeability

Constricts blood vessels

All of the following are actions caused by prostaglandins EXCEPT one. Which one is the EXCEPTION? -vasodilation and increased vascular permeability -elevated body temp -bronchoconstriction and smooth muscle contraction -decreased feeling of pain

Decreased feeling of pain

Prostaglandins will cause all of the following EXCEPT one. Which one is the EXCEPTION? -vasodilation -bronchoconstriction -decreased vascular permeability -increase feeling of pain

Decreased vascular permeablility

Healing by primary intention occurs when which one of the following conditions is met? -Antibiotics are taken to control infection -Edges of the wound are brought together by sutures -There is infection in the tissue -The wound has caused a large tissue defect

Edges of the wound are brought together by sutures

Fever

An increase in the number of white blood cells is called: Leukotrienes Leukocytes Leukocytosis Cytokines

Leukocytosis

Which of the following white blood cells is the main cellular responder in a viral infection? Monocytes Lymphocytes Macrophages Mast cells

Lymphocytes

Which of the following contain strong digestive enzymes that aid in digesting or eliminating phagocytized foreign matter? Phagosome Lysosomes PMN's Mast cells

Lysosomes

When chemical mediators cause the cells in the blood vessel walls to separate slightly and form microscopic gaps the cells become more: Permeable Marginated Dialated Constricted

Permeable

When leukocytes ingest and digest foreign matter the process is called: Leukocytosis Phagocytosis Pavementing Chemotaxis

Phagocytosis

Which of the following blood cells are the first to arrive at the scene of a traumatic injury? Basophils Foreign body giant cells Polymorphonuclear neutrophils Macrophages

Polymorphonuclear neutrophils

Toxins produced by bacteria

PMN's are the first cells to arrive in an area of acute inflammation and will try and neutralize the initial cause of the inflammatory process. PMN's are a type of Mast Cell. true, false false, true both true both false

true, false
