Wk1Ch2: Key Words Flashcards
Abscess
a build-up of pus that forms in the body’s tissues
acute gastritis
inflammation in the gastric mucosa often caused by the ingestion of irritants such as aspirin, alcohol or certain microorganisms
acute pancreatitis
a sudden inflammation of the pancreas
acute sinusitis
inflammation of the lining of the paranasal sinuses lasting 4 to 8 weeks
adhesions
a band of scar tissue that joins two internal body surfacesthat are not usually connected
arthritis
degeneration or inflammation of the joints
cellular response
the alerting of the products of healing to attend to the site of injury
chemotactic factors
specific inflammatory mediators
chemotaxis
the process of moving certain cells to the injury site
chronic inflammation
is presented as an altered inflammatory response because of unrelenting injury
chronic gastritis
a long-term condition that involves inflammation of the stomach lining
chronic pancreatitis
ongoing inflammatory process of the pancreas, characterised by irreversible cellular and tissue changes
cytokines
signalling proteins that help control inflammation in your body
Crohn disease
a chronic inflammatory bowel disease (IBD) that causes inflammation in the digestive tract
deep partial-thickness burns (second degree burns)
burns that damage the epidermis and penetrate into the dermis
degranulation
the process by which immune cells (such as mast cells) break apart and release inflammatory mediators int he form of extracellular granules (grain like particles)
dehiscence
splitting or bursting of a structure (wound), at a suture line
diapedesis
the process by which white blood cells, or leukocytes, pass through blood vessel walls and move into nearby tissues
differentiation
process by which immature cells become mature cells with specific functions (become specialised)
dyspepsia
indigestion
edema
swelling
erythema
redness
eschar
a dry black hardened area of dead skin that forms over a wound
exudate
the watery fluid that accumulates at the site of injury
fibroblasts
important cells that produce and replace the connective tissue layer
full-thickness burns (third degree burn)
damage the epidermis and dermis and can penetrate subcutaneous layers as well
gastritis
inflammation of the lining of the stomach or gastric mucosa
granulation tissue
a connective tissue characterised by extensive macrophages and fibroblasts, and the promotion of angiogenesis
granulomas
nodular inflammatory lesions that encase harmful substances
hematemesis
vomiting blood
hemostasis
the stopping of blood flow to form a clot
immune response
the body’s way of defending itself against harmful substances
inflammatory bowel disease (IBD)
chronic inflammatory processes most commonly in the small intestine and large intestine but can occur anywhere along the gastrointestinal tract from the mouth to the anus
inflammatory mediators
facilitate the process of widening and loosening the blood vessels at the site of injury
keloids
hypertrophic scars that result from excessive collagen production at the site of injury
labile cells
cells that divide and multiply constantly
pancreatitis
inflammation of the pancreas, resulting in destruction of the pancreas by pancreatic enzymes
rheumatoid arthritis (RA)
a systemic autoimmune disease characterised by chronic inflammation and hyperplasia of the synovial membranes with increased synovial exudate, leading to swelling and thickening of the synovial membranes, joint erosion, and pain
secondary intention
when wounds heal from the bottom up
primary intention
wound healing where the wound is basically closed with all areas of the wound connecting and healing simultaneously
proliferation
growth and reproduction
sepsis
your body’s extreme reaction to an infection
serous exudate
a clear fluid that seems out of the tissues (wounds)
sinusitis
symptomatic inflammation of the paranasal sinuses and nasal cavity
stable cells
cells that only multiply when needed
superficial partial-thickness burns (first degree burns)
burns that damage the epidermis
transudate
ultrafiltrate of plasma with low protein content and little or no cellular material
thrombus
protective clot and subsequent scab
ulcerative colitis
a chronic inflammatory condition of the colon
ulcers
sores in the lining of the stomach or small intestine
vascular response
the increased blood flow to the site of an injury
