Human Body in Health & Disease (Chapter 2) Flashcards
disease of rapid onset, short duration, w/ sharp/severe effect
acute
disease of long duration, typically slow in progression
chronic
state of the body where homeostasis has faltered
disease
disease induced by medical treatment
iatrogenic
disease of unknown cause
idiopathic
invasion & multiplication of parasitic organisms within the body (bacteria, viruses, fungi)
infection
response to trauma, marked by symptoms of redness, swelling, heat, & pain
inflammation
conditions following & resulting from disease
sequelae
wound or injury
trauma
computed axial tomography scan: diagnostic scan similar to x-ray where data from beams of energized particles are computer interpreted to produce a 3-D cross-sectional image of the body
CAT/CT scan
determination of the nature of a disease
diagnosis
diagnostic procedure involving visual exam w/ an endoscope - made up of camera, fiber optics, & long flexible tube inserted into patient
endoscopy
study of origin/cause of disease
etiology
evaluation made for purpose of diagnosis by identifying physical evidence of disease, such as signs and symptoms
examination
magnetic resonance imaging: diagnostic scan using a powerful magnetic field generated in a chamber where the patient lies - traces hydrogen thru patient’s body resulting in clear, complete computer generated 3-D images of soft tissue
MRI scan
