refers to the death of one or more cells or a portion of tissue or organ.
Necrosis
refers to a decrease in size of the cells
atrophy
the potential unwanted outcomes of the primary condition
sequelae
refers to an area of necrotic tissue that is associated with a lack or loss of blood supply followed by invasion of bacteria.
gangrene
probability for recovery or other outcomes
prognosis
normal programmed cell death; does not cause an inflammatory response
Apoptosis
increased number of cells causing an enlarged tissue mass
hyperplasia
period in which early in the disease one is aware of a change in the body but the signs are not specific; it's difficult to confirm a diagnosis
prodromal period
measure designed to preserve health and prevent the spread of disease
Prophylaxis
epidemics
reduced oxygen in the tissue
hypoxia
when one mature cell type is replaced by a different mature cell type; may be an adaptive mechanism
metaplasia
state in which pathologic changes occur but the patient doesn't exhibit obvious manifestations
subclinical state
what are the three types of gangrene
wet, dry and gas gangrene
indicates the disease rates within a group
morbidity
results in the lysis or dissolution of the cell, releasing destructive lysosomal enzymes into the tissue
pyroptosis
cells that are undifferentiated with variable nuclear and cell structures and numerous mitotic figures; basis to grade aggressiveness of tumor
anaplasia
described as a gradual progression with only vague or very mild signs
insidious onset
condition that triggers an acute episode
a precipitating factor
science of tracking the pattern or occurrence of disease
epidemiology
decreased supply of oxygenated blood to a tissue or organ due to circulatory obstruction.
ischemia
tissue in which cells vary in size and shape, have large nuclei and mitosis rate increases
dysplasia
collection of signs and symptoms affecting more than one organ and occur simultaneously
syndrome
which type of necrosis is related to the development of TB
caseous necrosis
the occurrence of disease is tracked by recording these two factors
incidence and prevalence
