Question | Answer |
---|---|
is the study of the speicifc characteristics and functions of a living organism and its parts | physiology |
suffering or disease | patho |
the study of the disorder or breakdown of the human body's fuctions | pathophysiology |
homeostatis, disease, and illness | key elements of pathophysiologis processes |
dynamic steady state, representing the net effect of all turnover reactions | homeostasis |
temperature, cardiac output, blood pressure, oxygen and carbon dioxide levels, acid-base balance, fluid volume, and electrolyte composition | parameters related to maintain homeostatis |
causes the controller to respond in a manner that opposes or negates deviation from normal (set point) level | negative feedback |
an initial disturbance in a system sets off a chain of events that does not favor stability and often abruptly displaces a system away from its steady-state operating point | positive feeback |
disruption of homestasis | disease |
genetic variations, cultural considerations, age differences, gender differences, situational differences, time variations, laboratory conditions, and baseline evaluations | various physiologic parameters |
12-16 g/100 ml of blood | normal women's range for hemoglobin concentration |
13-18 g/100 ml og blood | normal men's range for hemoglobin concentration |
clacium ranges are slightly higher in ____ | women |
Erythrocyte sedimentation rate | ESR |
less than 13mm/hr | men's ESR |
around 13mm/hr | women's ESR |
0.4 to 1.3 mg/dl | women's normal serum creatinine level |
0.6 to 1.5 mg/dl | men's normal serum creatinine level |
____snore more, have longer vocal cords, better daylight vision, higher metabolic rates, and are more likely to be left handed | males |
RBO count increases when a person moves to a higher altitude, this is a normal adaptive response to the decreased availability of oxygen at a high altitude | acclimatization |
factors that vary according to the time of day | circadian rhythm or diurnal variation |
age, gender, genetic and ethnic background, geographic area, and time of day | variations in physiologic processes |
the mechanisms of its development | etiologic process |
etiologic process, pathogenesis, and clinical manifestations | three aspects of a disease process that form a framework for understanding pathophysiology |
structural and biochemical alterations induced in the cells and organs of the body | pathogenesis |
functional consequences of changes | clinical manifestations |
an expression of altered chemistry, and dystunction is an inevitable consequnce | structure |
the study of the causes or reasons for phenomena | etiology |
when the cause is unknown | idiopathic |
when the cause is due to an unintended or unwanted medical treatment | iatrogenic |
requires the unusual environment of premature birth and high oxygen concentration, which causes damage ot the retina, resulting in blindness | retrolental fibroplasia |
common disease involving many genotypes and a variety of environmental agents | coronary arteriosclerosis |
an inherited condition that causes red blood cells to form sickle shapes when the oxygen concentration is low--leads to headaches, dizziness, and pain in the abdomen whe the sickled erythrocytes plug small blood vessels in the brain and liver | sickle cell anemia |
genetic makeup and environmental interaction | the two causes of human disease |
the "survival of the fittest" idea that is a struggle between nature (genetic makeup or inheritance) and nurture (environment) is ongoing | ecogenetics |
inherited, congenital diseases/birth defects, metabolic, degenerative, neoplastic, immunologic, infectious, physical agent-induced, nutritional deficiency, iatrogenic, psychogenic, and idiopathic diseases | etiologic classification of diseases |
are responsible for most neonatal deaths | prenatal influences |

when the immune system overreacts | ex: hypersensitivity reaction |
immune system attacks one's own body | autoimmune response |
when the immune system underreacts | ex: AIDS |
disease-causing organisms that damage the body in some way | pathogens |
any organism that lives in or on another organism to obtain its nutrients | parasite |
an intestinal loop can slip through a defect in the abdominal wall and become trapped | hernia |
the most common cause of death in developing countries | TB and malnutrition |
emotional factors | psychogenic |
