Compare and contrast signs and symptoms 3. Sensitivity is to false positive as and abnormal in the context of true positive, false positive, true negative, and false negative. relationship between structure and function is to false negative s to true positive

Answer 1

9,a, incidence

Incidence is the rate of new case of the disease

10, d, multifactorial

Coronary heart disease is the leading cause of death..it is a multifactorial disease.

11, structure is a arrangement of parts in an organism..it includes shape,material of which the part is made.

Function is the job of part does..for example bone and muscle together make body movements

12, symptoms can only feel by particular person..that is feeling..if you have pain only you can know others can not feel that.

Signs can be seen by others rather than felt.. example pulse, temperature,blood pressure.

sometime signs indicate symptoms for example when people feel nausea they will vomit.in most of the medical condition both signs and symptoms that help to diagnose the disease..

13, B, specificity is to true positive

False positive means the Patient does not have the disease but the test is positive

14, due to changes in living condition in environment and longer life expectation influenced with genetic disorders example diabetes,chronic pulmonary disease, Parkinson's syndrome etc.

15, Anatomical pathology involved examine patient specimen after the procedure like biopsy of cells,organs, tissues

Clinical pathology involved the laboratory evaluation of body fluids like blood,urine or cerebrospinal fluid etc..
