Pathophysiology From Ch. 1 Of Clinical Concepts Of Disease Processes

Front 1

pathology

Back 1

the science of study of disease

also a clinical specialty in human medicine

Front 2

2 divisions of pathology

Back 2

anatomic pathology

clinical pathology

Front 3

anatomic pathology

Back 3

surgical, cytolog, necropsy

Front 4

clinical pathology

Back 4

clinical chemistry, clinical microbiology, hematology, blood bank, immunology

Front 5

pathology emphasizes

Back 5

emphasizes the measurable aspects of disease, such as altered structure of cells, tissues, and organs (gross & microscopic) and lab findings

Front 6

pathology draws from what sciences?

Back 6

basic and clinical sciences; anatomy, physiology, biochemistry, cell and molecular biology, genetics, pharmacology, and pathology

Front 7

how is pathophysiology different from other biomed sciences?

Back 7

focus on the mechanisms of disease or the dynamic processes the give rise to the signs and symptoms

Front 8

why do health care practitioners need to understand the mechanisms of disease?

Back 8

interpretation of signs and symptoms, appropriate treatment, and prevention are logically related to knowing the disease

Front 9

normal and disease

Back 9

are complex and to an extent arbitrary and influenced by cultural values, as well as biologic factors

Front 10

define disease

Back 10

a failure of the organism to adapt or to maintain homeostasis; it is actually the sum of the physiologic processes that have been distorted

Front 11

where does disease come from

Back 11

often disease begins within the adaptive mechanisms of the body that have the potential to result in a good or bad outcome

Front 12

etiology

Back 12

- the study of causes or reasons for phenomena

- complex b/c most diseases are multifactorial and result from an interaction of intrinsic or genetic and environmental factors

Front 13

knowing the cause of disease is important because...

Back 13

without knowing the cause prevention would be very difficult

Front 14

pathogenesis

Back 14

the sequence of events in the development of a disease from its earliest beginnings, including factors influencing its development

Front 15

natural history of a disease

Back 15

its usual course from beginning to end without treatment

Front 16

lesion

Back 16

a demonstrable structural change in the tissues produced by disease that is evident at a gross or microscopic level

Front 17

signs

Back 17

observable (objective) clinical manifestations of disease, such as a heart murmur, hypertension, fever or a palpable mass

Front 18

symptoms

Back 18

subjective feelings that something is wrong and can be reported only be the patient to an observer
ex. pain, nausea, vertigo, lethargy

Front 19

sequela, sequelae (pl.)

Back 19

the outcome or aftereffect of a disease or injury

ex. the sequela of acute rheumatic fever might be scarred and deformed heart valves

Front 20

complication of disease

Back 20

an accidental condition or second disease occurring in the course of a primary process

Front 21

resolution

Back 21

the subsidence of a disease process, as inflammation, and the return to normal of affected tissues

Front 22

classification of diease

Back 22

organ system or etiologic categories

any disease may include more than one category at one time
