result of increased cell division

24
Q

Hypertrophy

Study These Flashcards
A

enlargement of a tissue/organ
resulting from an increase in the size of its individual cells
NOT in number of cells

25
Inflammation
nonspecific response involves microcirculation and its blood cells
26
Keloid
excessive scarring mainly occurs in skin in some cases of healing
27
Leukocytosis
increase in number of WBC's in circulating blood
28
Leukopenia
Condition abnormally low levels of WBC's in circulating blood
29
Local
disease process confined/limited to a specific location NOT systemic or general
30
Lymphadenopathy
abnormal enlargement of lymph node(s)
31
Macrophage
large tissue bound mononuclear phagocyte derived from monocytes can be mobile with inflammation interacts w/ lymphocytes in immune response for inflammation
32
Margination
process during inflammation where WBC's tend to move to the periphery of blood vessels at the site of an injury
33
Microcirculation
small blood vessels, arterioles, capillaries, and venules of the vascular system
34
Myofibroblasts
fibroblasts w/ some characteristics of smooth muscle cells ex: ability to contract
35
Necrosis
pathological death of one or more cells results from irreversible damage to the cells
36

enhancement of phagocytosis by a process in which a pathogen is marked for destruction by phagocytes
39
Osteoblasts
cells the form bones
40
Parulis
collection of granulation tissue and abscessed material on the gingiva originates from chronically inflamed tooth spreads via fistulous tract aka gum boil
41
Pavementing
adherence of WBC's to blood vessel walls during inflammation
42
Perimolysis

Regeneration
process by which injured tissue is replaced w/ tissue identical to that present before the injury
48
Serous exudate
exudate that has a watery consistency resembles serum
