Intro to Path and Pathophys Flashcards
Pathophysiology
study of the disruption of normal bodily function (homeostasis) due to disease or physiology of abnormal function
Pathology
study of structural or morphological abnormalities which are expressed as diseases of cells, tissues, organs and whole systems
Disease
an impairment of cells, tissues, organs, or body system functions of the body, which poses challenge to body homeostasis
Body homeostasis
dynamic steady state marked by appropriate regulatory responses by the body…aka Health!
Etiology
cause of a disease or disorder (genetic, acquired, or infectious, etc).
Idiopathic cause
- unidentifiable cause
- “idiots for not knowing”
Iatrogenic cause
result of medical treatment
Nosocomial diseases
hospital-acquired infectious disorder
Congenital Berry Aneurysm
- congenital disorder at the bifurcation of the Circle of Willis
- Subarachnoid hemorrhage causes headaches and photophobia
Acute disease
- severe disorder, quick onset, self-limiting w/signs and sxs
- i.e. acute MI
Chronic disease
- long-term, continuous disease process characterized by exacerbations and remissions
- usually not curable
- i.e. chronic ulcerative colitis
Subacute disease
somewhere between acute and chronic timeframes
Carrier state
- pt harbors an organism, NO signs or sxs but can transmit the disease
- i.e. “Typhoid Mary”
Syndrome
group of clinical sxs and physical features that characterize a particular disorder
Down Syndrome (Trisomy 21)
- protruding/big wrinkled tongue, Brushfield spots & Epicanthal fold (facial features), congenital heart disease, Simian crease (hands), wide gap between 1st and 2nd toes
