Term. test 1

Pathophysiology The study of how disease affects body function.
Pathology The study of changes in cell/tissue structure related to disease or death.
Health Having the ability to maintain homeostasis when exposed to normal conditions.
Disease Being unable to maintain homeostasis when exposed to normal conditions.
Etiology The study of the cause of a disease.
Genetic A disease, condition, or trait that is inherited as a result of a single gene.
Congenital A disease, condition, or trait that is present at birth.
Acquired A disease, condition, or trait that developed because of being exposed to something during your life.
Idiopathic Without a clearly identified cause.
Signs Evidence of disease that is objective and can be seen, measured, or recorded.
Symptoms Evidence of a disease that is subjective and cannot be seen, measured, or recorded.
Pathogenesis The events that lead to the development of a disease and the signs and symptoms that occur as the disease progresses.
Acute A disease that develops and resolves rapidly.
Chronic A disease that develops gradually and lasts 3 months or longer.
Remission The lessening in severity of the symptoms of a disease.
Exacerbation An increase in the severity of a disease or any of its signs or symptoms.
Local A condition that is confined to one area.
Systemic A condition that affects the entire body.
Endoscopy A procedure that utilizes a fiber optic camera to view structures inside of the body.
Radiodensity The ability of an object to stop or slow radiation.
X-ray A visual recording of differences in radiodensity of anatomical structures.
Contrast X-ray X-rays that utilize a contrast media to increase the radiodensity of selected fluids within the body, producing an image of the structures containing the fluid.
Ultrasound A visual recording of differences in the rate of return and intensity of sound waves reflected off of objects within the body.
Electrocardiogram A recording of the electrical activity of the cardiac conduction system.
Electroencephalogram A recording of the electrical activity of the brain, most often recording the cerebral cortex.
Spirometry Any procedure used to measure a persons ability to move air or the capacities of the respiratory system. Often referred to as PFT's (pulmonary function tests)
Chemotherapy The use of chemicals to kill cells within the body. Two main types of chemotherapy are used-to kill cancer cells or microorganisms.
Pharmacological The use of drugs to treat disease.
Palliative Any form of treatment that relieves signs and symptoms without curing a disease. May include the use of medication (such as decongestant or pain reliever), therapeutic massage, counseling, physical therapy, orthotic devices, etc.
Prognosis A prediction of the likely outcome or consequence of having a disease.
Sequela A consequence of a previous disease (Ex: rheumatic heart disease sometimes occurs following a strep infection)
Complications A morbid process or event occurring during a disease that is not an essential part of the disease, although it may result from it. (Ex: blindness is a complication often associated with diabetes)
Terminal A disease likely to cause death.
Trauma The transfer of a harmful amount of energy. The energy may be mechanical, electrical, radiation, or thermal.
Deficiency Lacking in something that is essential. (Vitamin, glucose, protein, oxygen, water, etc)
Intoxication Being exposed to a toxic level of something.
Hypertrophy To increase in size.
Atrophy To decrease in size.
Hyperplasia An increase in the rate of mitosis and therefore cell number.
Metaplasia A change in cell or tissue structure.
Dysplasia Irregular cell or tissue structure. Often considered a potentially cancerous change.
Neoplasia Growth of cells and tissue into new areas, resulting in a tumor. May be benign or malignant.
Inflammation A protective response of tissue to injury or infection. Causes an increase in blood flow and pain in the affected region, as well as leokocytosis.
Pyrogens Chemicals that cause a fever.
Leukocytosis An increase in the number of white blood cells to more than 10,000 per mm. A WBC count of 15,000-25,000 commonly occurs as a result of infection, inflammation, or hemorrhage.
Exudate The excess fluid that accumulates at the site of inflammation. Contains a high level of proteins and neutrophils when compared to normal tissue fluid.
Serous Exudate A thin, clear, watery fluid that accumulates at the site of inflammation.
Purulent Exudate A thick, creamy, white or yellow fluid that accumulates at the site of inflammation. Also called pus.
Suppurative Inflammation A response to injury or infection that leads to the production of pus.
Regeneration Replacing damaged tissue through the process of mitosis, restoring the tissue to its original condition.
Repair Replacing damaged tissue with scar tissue.
Adhesions The binding together of two surfaces by scar tissue.
Keloid Scarring The over production of scar tissue that sometimes occurs in the dermis and subcutaneous layer and results in a mass of scar tissue that is often tender or painful.
Contracture The shortening of scar tissue over time OR the shortening of muscle tissue as a result of fibrotic changes.
Stenosis The narrowing of any canal or opening, such as the intestine, or a blood vessel of a heart valve.
Sclerosis The process of hardening. Can occur as the result of scar formation or the accumulation of deposits known as plaques.
Necrosis Tissue death.
Prodromal Stage An early stage in the development of a disease or infection that is characterized by a lack of appetite and lack of energy. The time when a person feels as if they are "coming down with something".
Anaphylaxis A severe, systemic, allergic response that is characterized by vasodilation (which causes a severe drop in blood pressure) and bronchoconstriction (resulting in severe difficulty in breathing).
Immunosurveillance The immune system's constant search for an antigen.
Immunotolerance The immune system's ability to recognize and not attack normally occurring tissues within the body.
Incubation The development of an infection from the time the infectious organism enters the body until the appearance of the first clinical signs and symptoms.
Acute Stage The time during an infection when clinical signs and symptoms begin to develop.
Benign A nonmalignant neoplasm.
Malignant A cancerous neoplasm.
Angiogenesis The development of new blood vessels, especially capillaries.
Tumor Markers Proteins produced by tumor cells that can be detected in screening tests of the person's blood.
Carcinoma A malignancy that originates in epithelial tissue.
Sarcoma A malignancy that originates in connective tissue.
Glioma A malignancy that originates within the tissue of the central nervous system.
Carcinogenesis The process of developing a malignant neoplasm.
Initiators (of cancer) Carcinogens that increase the rate of cancer cell production by activating oncogenes.
Promoters (of cancer) Carcinogens that decrease the body's ability to find and fight cancer cells by damaging tumor suppressing genes.
