Pathophysiology Chapter 1 Text Terms

The study of functional or physiologic changes in the body that results from the disease process

The laboratory study cell and tissue changes associated with disease

A medication that lacks active ingredients, prescribed for physiological effects or as part of research studies. A sugar pill

The identification of a specific disease

The causative factors in a particular disease

Measues preserving or preventing the spread of a disease

The development or sequence of events involved in the tissue changes of a specific disease process

How the disease presents itself, sudden and acute or insidious and chronic

A disease whose onset is marked only by vague or mild symptoms

A disease whose onset is sudden and has a short course

A condition with insidious, mild, or slow onset but with continuous progressive manifestations and long lasting effects

The disease is present but the patient has no signs or symptoms

Silent or incubation period

The time between exposure to a disease and the onset of signs and symptoms

The early stages of the disease where the signs and symptoms are general in nature, the patient just feels bad

The clinical evidence or effects of a disease, the signs and symptoms

The signs and symptoms are found at the site of a problem

Signs and symptoms that are just general to a lot of diseases

Objective indicators of a disease obvious to someone besides the patient

Subjective feelings of the patient life pain or nausea

An abnormality in the structure of a tissue or organ

A group of signs and symptoms characteristic of a specific disease

An acute episode or increased severity of manifestations

A period or condition in which manifestations of the disease subsides, either permanently or temporarily

A condition that triggers an acute episode

New secondary or additional problems that arises after the original disease begins

Potentially unwanted outcomes of the disease, ex: hemiparesis after a stroke

The probable outcome of a disease

The rate in which a disease occurs; the portion of a group affected by a disease

The number of deaths in a group for a specific disease

The science of tracking the pattern or occurrence of a disease

The incidence and prevalence of a disease

The number of new cases of a disease in a certain population within a given time period

The total number of new and existing cases of a disease in a specific population at a given time

A disease occurring in higher numbers than usual in a certain population within a given period

A worldwide increase in the numbers of people affected by a disease

Infections that can be spread from one person to another

A decrease in the size of a cell

Increase in size of individual cells

The increase in the number of cells

Replacement of one mature cell with another type

Disorganized cells that vary in size and shape with a large nuclei

Undifferentiated primitive cells of variable size and shape, associated with cancer

New growth

Abnormal growth of new cells, benign or malignant aka tumor

Non-threatening, mild, or nonmalignant

Cancer

The process by which dead cells liquefy under the influence certain cell enzymes, usually brain tissue or certain bacteria infection

Liquefaction

Liquefaction

Occurs when the cell proteins are altered or denatured, similar to cooked egg whites, typically Occurs with a myocardial infarction

Coagulative necrosis

Occurs when fatty tissue is broken down into fatty acids in the presence of infection or certain enzymes

A form of coagulation necrosis in which a thick, yellow, "cheesy" substance forms. Found in TB

Caseous necrosis

An area of dead cells resulting from the lack of oxygen

No, dead tissue is replaced by scar tissue

Often caused by coagulative necrosis in which the tissue dries, shrinks, and blackens

Results with liquefaction causing the tissue to become cold, swollen, and black

Caused by the build up of gases within the tissue and further reducing the blood supply
