Pathology - ANSWER: The study of disease that can cause
abnormalities in the structure or function
of various organ systems.
Disease - ANSWER: The pattern of the body's response to some form of injury that
causes a deviation from or variation of normal conditions
Pathogenesis - ANSWER: The manner of the development of a disease
Acute Disease - ANSWER: Generally develops suddenly and lasts a short time and are
often caused by a virus or infection, traumatic injury, or misuse of medication or
drugs.
Chronic Diseases - ANSWER: Develop slowly and may worsen over an extended
period of time. Often caused by unhealthy behaviors that increase the risk of disease
like poor nutrition, inadequate physical activity, overuse of alcohol or smoking.
Social, emotional and environmental and genetic factors also play a role as people
age.
Manifestations - ANSWER: A set of characteristics known as signs or symptoms
resulting from the disease process
Signs - ANSWER: Measurable or objective manifestations that can be identified or
observed by another person. An example would be vital signs.
Symptoms - ANSWER: Subjective manifestations such as pain or loss of smell or
taste.
Asymptomatic - ANSWER: Having no signs or symptoms while having a disease
Diagnosis - ANSWER: The identification of the nature of an illness or the precise
disease process affecting the patient
Prognosis - ANSWER: Expected outcome based on the diagnosis and the etiology
Etiology - ANSWER: The underlying cause of the disease
Idiopathic - ANSWER: When the etiology of a disease is unknown
Syndrome - ANSWER: A condition characterized by group of signs, symptoms and
disease processes
, Mortality - ANSWER: The number of deaths caused by an illness or event over a
specific period of time
Morbidity - ANSWER: Any condition that isn't healthy, whether it be a physical or
mental Illness
Incidence - ANSWER: The number of individuals who develop a specific disease or
experience a specific health-related event during a particular time period
Prevalence - ANSWER: The total number of individuals in a population who have a
disease or health condition at a specific period of time, usually expressed as a
percentage of the population
Acute inflammation - ANSWER: The tissue's initial response to an injury from trauma,
infectious organisms or exposure to irritating chemical substances
First phase of Inflammatory Process - ANSWER: The arterioles and capillaries and
venules dilate causing hyperemia which results in redness and heat. The hyperemia
then causes the venules and capillaries to become permeable allowing a protein rich
plasma that crosses the vessel walls into the interstitium causing swelling which
causes pressure on the nerve endings resulting in pain.
Hyperemia - ANSWER: rush of blood flow that occurs in inflammatory process.
Phagocytosis - ANSWER: Process by which white blood cells enzymatically digest
infecting organisms and cellar debris in inflammatory process.
Granulation tissue - ANSWER: Combination of developing capillaries and proliferating
or multiplying fibroblasts, which produce connective tissue fibers, collagen, that then
replaces dead tissue.
5 Clinical Manifestations of Inflammation - ANSWER: Rubor (redness), Calor (heat),
tumor (selling), Dolor (pain), and loss of function.
Suppurative Inflammation - ANSWER: Inflammatory response that occurs when
bacterial organisms produce toxins and then damage the tissues, producing pus,
inflammatory exudate and bacteria.
Edema - ANSWER: Accumulation of abnormal amounts of fluid in the intracellular
tissue spaces or body cavities.
Localized Edema - ANSWER: Edema that occurs from an inflammatory
reaction/response causing the escape of protein-rich intravascular fluid into the
extravascular tissue or from from an obstruction to lymphatic drainage.
