Questions And Answers Rated A+.
Homeostasis - Answer Relatively stable internal conditions under fluctuating environmental conditions.
In homeostasis, the body's organ systems normally maintain temperature, pH, blood composition, and
fluid levels within a precise range and cor- rect any fluc
disease - Answer a deviation from normal structure or function in the body that interrupts or modifies
the performance of vital functions. For example, the amount of glucose in the blood is tightly regulated
to ensure that organs receive an adequate supply of energy.
Pathology - Answer Study of disease, epecially the structural and functional changes assoicated with
causes, mechaisms, signs, and symtpoms, treatments and prevention.
Health - Answer is the condition in which the human body per- forms its vital functions normally. In
health the body's various organ systems function optimally and a person can participate fully in his or
her life.
Prognosis - Answer a disease predicted course and outcome. The prognosis may state the chances for
complete recovery, predict the permanent loss of function, or give probability of survival.
Diagnosis - Answer the process of identifying a disease or disorder. Several types of information are
used for diagnosis, including signs and symptoms, which can be quite specific and therefore helpful for
diagnosing certain diseases.
Acute Disease - Answer has a sudden onset and short duration. Influenza, measles, and the common
cold are examples of acute infections.
Terminal - Answer Disease that will end in death.
Chronic Disease - Answer has a slower, less severe onset and a long dura- tion of months or years.
Examples of chronic diseases include heart disease, cancer, stroke, diabetes, and arthritis.
,Exacerbation - Answer Signs and symptoms may grow more severe.
Relapse - Answer The return of a disease weeks or months after its apparent cure.
Complication - Answer interfers with recovery from the original disease.
Sequela - Answer aftermath of a particular disease. Example sequel of polio is paralysis.
Remission - Answer signs and symptoms subside or disappear
Mortality - Answer Number of deaths that occur among people with a certain disease
Morbidity - Answer is the number of cases of a disease in a population
Prevalence - Answer is a percentage of a population that is affteced with a particular disease at a given
time
Incidence - Answer The number or rate of new cases of a particular condition during a specific time.
Idiopathic - Answer a diseas that is not known is said to be.
Pathogenesis - Answer Cause of a disease leads to the anatommical and physiological changes in the
body that ulimately result in disease
Etiology - Answer important aspect of any disease
Palliative - Answer Provide comfort and relieve pain.
Phagocyte - Answer ingest and engulf foreign antigens and the
, leukocytes that belong to this category
Interferons - Answer Antiviral proteins produced by some animal cells after viral infection. Stimualte
nearby cells to fight infection. Increase activity of natural killer cells and macrophages.
Phagocytes - Answer Leukocytes (WBC)
Pathocytosis - Answer Leukocytes (white blood cells) such as macrophages and neutrophils can engulf
and destroy pathogens
Plasma - Answer contains the protein albumin, which promotes the blood's ability to hold water and
maintain pressure inside the blood vessels.
Histamines and kinins - Answer After an injury, damanged cells release potentional chemical signals
such as _________ causing teh chemicals in the blood vessel to dilate and become more permenable,
which causes cardunal signs and symtpoms of inflammations: redness, heat swelling, and pain.
Complement - Answer a group of plasma proteins that assist in the destruction of foregin cells. These
cells are in inactive state that, but when activated by bacteria cause tehm a casade of biochemical
ewactions leading to lysis. Helps nonspeific and specific immunity.
Humoral immunity - Answer is due to the action of antibodies, which are proteins produced by white
blood cells called B lymphocytes (or B cells). Antibodies (which are also called immunoglobulins) provide
a defense against extracellular antigens such as bacterial toxins and bacterial cells.
Cell-mediated immunity - Answer provides a defense against viruses, abnormal cells, and other
intracellular pathogens, and it is the arm of the immune system responsible for rejecting tissue grafts
and organ transplants. T lympho- cytes (or T cells) are responsible for cell-mediated immunity.
Memory B cells - Answer responsible for a more potent and rapid antibody response during
subsequent exposures to the same antigen.
