Inflammation (Q2,Ch.5) Flashcards
(35 cards)
Inflammation
An immunological defense against injury, infection, or allergies, marked by increases in regional blood flow, immigration, white blood cells, and releases a chemical toxins
The body’s attempt to contain, and eliminate the initial cause of injury to the cells; essential to the removal of dead in the product issues, resulting from the original injury
Signs of inflammation: tumor, calor, rubor, dolor, Functio Laesa
Vasodilation
The increase in the diameter of vessels
Tumor
Common name: swelling
Increased permeability of vessels
Calor
Common name: heat
Cause: Vasodilation (blood vessels expand)
Rubor
Common name: redness
Cause: vasodilation (blood vessels expand)
Dolor
Common Name: pain
Cause: nervous stimulation and swelling
Functio Laesa
Common name: altered function for loss of function
Cause: swelling and pain
Acute inflammation
The first phase of inflammation
Short duration (days)
The body’s attempt at regenerating cells and restoring them to normal function with no residual effects
Chronic inflammation
The progression of acute inflammation
- Characterized as having a long duration (days-years)
Serous infection
Exudation of clear fluid with few cells
Fibrinous inflammation
Fibrin rich exudate
Purulent inflammation
Exudate rich in Pus
Ulcerative inflammation
Loss of epithelium resulting in ulcerous lesion
Pseudomembranous inflammation
Ulceration and a pseudomembrane over the ulcer
Chronic inflammation
Active inflammation, tissue destruction, and the presence of an inflammatory exudate containing lymphocytes and macrophages
Granulomatous inflammation
Specialized form of chronic inflammation characterized by the formation of granulomas (accumulation of chronic inflammatory cells)
Chemo taxis
The movement of white blood cells to an area of inflammation in response to the release of chemical mediators by neutrophils, monocytes, and injured tissues
Phagocytosis
A process in which phagocytes (neutrophils, monocytes, and macrophages) engulf and destroy microorganisms, other foreign antigens, and cell debris
Lesion
Specific pathologic structural or functional change brought about by disease
Abscess
A localized accumulation of pus
Ulcer
An OPEN SORE or lesion of skin or mucus membrane, accompanied by sloughing off of inflamed, NECROTIC TISSUE
Vesicle
Blister like elevation of skin containing serous fluid
Furnuncle
Boil; an abscess or pustular infection of a sweat gland, or hair follicle
Carbuncle
Several communicating boils of the skin and subcutaneous tissues that produces and discharges pus and dead tissue
