Disease Process and Terminology Flashcards
Asymptomatic
Showing no symptoms of disease
Homeostasis
Stability of the body
Pathogenesis
Development of disease
Acute
abrupt
Chronic
Lasts longer than six months
Predisposing factors (risk factors)
Makes a person/group more vulnerable to disease
ex: age, lifestyle, gender, environment, hereditary
Acute inflammation
normal protective response to injury/disease, accompanied with redness, heat, swelling, pain, and loss of function
Widespread inflammation
Marked by fever, malaise, and loss of appetite
Necrosis
Death of tissue
