Flashcards in Intro to Pathophysiology & Cell Injury Ch. 1 Deck (46):
1

The study of functional or physiologic changes in the body that result from disease process.

Pathophysiology

2

Deviation from the normal state of health or from a state of wellness.

Disease

3

Relativity stable or constant maintenance of the internal environment.

Homeostasis

4

The identification of a specific disease evaluation of signs and symptoms and laboratory tests.

Diagnosis

5

Concerns that causative factors in a particular disease.

Itiology

6

Cause of a disease is unknown

Idiopathic

7

When a treatment, procedure, or error causes a disease.

Iatrogenic

8

Vaccines, Dietary or Lifestyle Changes, Cessation of harmful activities, and removal of harmful materials from the environment.

Prevention Measures

9

Gradual progression with only vague or very mild signs.

Insidious

10

The development of a disease or the sequence of events involved in the tissue changes related to the specific disease process.

Pathogenesis

11

Indicates a short term illness that develops quickly with marked signs.

Acute Disease

12

Often a milder condition developing gradually, but it persists for a long time and usually causes more permanent tissue damage.

Chronic Disease

13

"Silent" stag, in which no clinical signs are evident. May be referred to incubation period.

Latent Stage

14

The time in the early development of a disease when one is aware of a change in the body, but the signs are nonspecific.

Prodromal Period

15

Clinical evidence or effects, signs and symptoms of disease.

Disease Manifestations

16

Found at site of the problem.

Local

17

General indicators of illness.

Systemic

18

Objective indicators of disease that are obvious to someone other than the affected individual.

Signs

19

Subjective feelings reported by patient.

Symptoms

20

When manifestations of disease subside.

Remission

21

When signs of disease increase. (Flare-ups)

Exacerabtion

22

A collection of signs and symptoms that usually occur together in response to a certain condition.

Syndrome

23

Condition that triggers an acute episode.

Precipitating Factor

24

New secondary or additional problems that arise after the original disease begins.

Complications

25

Period of recovery and return to the normal healthy state.

Convalescence

26

Defines the probability for recovery or for other outcomes.

Prognosis

27

Indicates the disease rates within a group.

Morbidity

28

Indicate the relative number of deaths resulting from a particular disease.

Mortality

29

Science of tracking the pattern or occurrence of disease.

Epidemiology

30

Many cases of an infections disease within a given area.

Epidemics

31

Involve cases over several regions or world-wide.

Pandemics

32

Number of new cases in a given population noted within a stated time period.

Incidence

33

Number of new and old or existing cases within a specific population and time period.

Prevalence

34

Apoptosis

Programmed cell death.

35

Necrosis

Death

36

Hypoxia

Reduction in oxygen to the cell

37

Anoxia

Loss of oxygen

38

Atrophy

Decrease in size of cells.

39

Hypertrophy

Increase in size of cells.

40

Hyperplasia

Increase in number of cells.

41

Metaplasia

When one mature cell type replaces a different mature cell type.

42

Dysplasia

Tissue in which cells vary in size and shape.

43

Anaplasia

Cells that are undifferentiated and have variable nuclei and cell structure.

44

Neoplasm

"New Growth" - Tumor.

45

Ischemia

Lack of blood supply to an area of tissue or part of an organ, can cause injury to cell death.

46

Mechanical Damage

Pressure/tearing off tissue.
