Textbook Chapter 5 Flashcards
Abcess
Localized pocket of purulent exudate or pus in a solid tissue
Adhesions
Bands of scar tissue joining two surfaces that are normally separated
Angiogenesis
Development of new blood vessels
Chemical Mediators
Released when tissue injury occurs by damaged mast cells. Can be histamine, serotonin, prostaglandin, leukotrienes into the interstitial fluid and blood.
Chemotaxis
Migration of cells toward attractant chemicals or away from repellents
Collagen
Collagen accounts for 30% of your body’s protein. It provides structure, support or strength to your skin, muscles, bones and connective tissues.
Contracture
Fixation and deformity of the joint that occurs after damage
Diapedesis
Passage of blood cells through the intact walls of the capillaries, typically accompanying inflammation.
Erythrocyte Sedimentation Rate
Blood test that can reveal inflammatory activity in your body (RBC sink to bottom)
Exudate
Collection of interstitial fluid formed in the inflamed area
Fibrinogen
Circulating plasma protein
Fibrinous
Exudates are thick and sticky and have high cell and fibrin content
Fibroblast
Connective tissue cells that produces collagen
Glucocorticoids
Granulation Tissue
Granulation tissue is vascularized tissue that forms as chronic inflammation evolves.
Granuloma
Small mass of cells with a necrotic center and covered by connective tissue
Hematocrit
A hematocrit test (Hct) is a simple blood test that measures the percentage of red blood cells in your blood
Hematopoiesis
Production of blood cells and platelets, which occurs in the bone marrow.
Hyperemia
Increased blood flow to the area
Interferons
Nonspecific agents that protect uninfected cells against viruses
Intraarticular
Within, occurring within, or administered by entry into a join
Isoenzymes
Two or more enzymes with identical function but different structure.
Leukocyte
WBC
Leukocytosis
Increased WBC in blood
Macrophage
Macrophages are specialized cells involved in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In addition, they can also present antigens to T cells and initiate inflammation by releasing molecules (known as cytokines) that activate other cells.
Malaise
Feeling of discomfort, illness, or uneasiness whose exact cause is difficult to identify.
Neutrophil
Neutrophils are a type of white blood cell. They make up the biggest number of all kinds of white blood cells.
Perforation
Hole that develops through the wall of a body organ
Permeability
Membrane allow liquids or gases to pass through it.
Phagocytosis
Process by which neutrophils and macrophages randomly engulf and destroy bacteria, cell debris, or foreign matter
Purulent
Exudates are thick, yellow/green, and contain more leukocytes and cell debris as well as microorganisms
Pyrexia
Low grade or mild fever
Pyrogens
Fever producing substances
Regeneration
Healing process that occurs in damaged tissue in which the cells are capable or mitosis.
Replacement
Scar (connective tissue) forms when there is excessive damage and the cells are incapable of mitpsis
Resolution
Process that occurs when there is minimal tissue damage
Serous
Watery exudates consists primarily of fluid with small amounts of protein and WBC
Stenosis
Shortening or narrowing of structures like tubes or ducts
Ulcer
A sore that develops on the lining of the esophagus, stomach, or small intestine.
Vasodilation
Relaxation of the smooth muscle causing a increase in diameter of arterioles
