concept of disease Flashcards
physiology
science that deals with function of the body and its parts
pathophysiology
study of disordered function
pathogenesis
development of disease
etiology
study of the cause of any disease
idiopathic
self-originating, without a known cause
symptoms
changes in body function felt by patient
sign
chenges in body function observed by others
syndrome
characteristic group of signs and symptoms
polydipsia
extreme thirst
polyuria
excessive urination
polyphagia
excessive appetite
sequelae
outcome of the disease (impairments that follow or are actually caused by the disease process)
latrogenic
adverse condition in a patient induced by treatment
insidious
gradual and subtle development
exacerbation
increase in the severity of a disease or any of its signs or symptoms
congenital
conditions that exist at birth
homeostasis
maintenance of constant conditions in the internal environment
how to maintain homeostasis
feedback systems
negative feedback system
input produces response in opposite direction
positive feedback system
input produces response in same direction
disease results when
homeostasis cannot be maintained and regulatory feedback system fails
serum sodium values
135-145 mEq/L
serum potassium values
3.3-5 mEq/L
Hemoglobin values
12-17 g/dl
chronobiology/chronotherapeutics
synchronize medications with biological rhythms to optimize treatment outcomes an minimize side effects
