|
|
Epidemlology
|
the study of the occurance, distribution and transmission of diseases in humans
|
|
|
Endemic
|
a disease that is native to a local region
EX: rocky mtn fever |

study the mechanic of the disease
|
|
|
MECHANISMS OF DISEASE
|
1. gentic
2. pathogenic organisms 3. tumors and cancer 4. physical and chemical agents 5. malnutrition 6. autoimmunity 7. inflammation 8. degeneration |
|
|
Genetic mechanisms
|
altered or mutated genes can cause adnormal proteins to be made resulting in the absense of an essential function
|
|
|
Pathogenic organisims
|
parasited or other organisms that invade us
|
|
|
tumors and cancer
|
abnormal tissue growth
|
|
|
Physical and chemical agents
|
toxic chemicals- drugs/alcohol
|
|
|
Malnutrition
|
Insufficent of inbalanced intake of nutrients
|
|
|
Autoimmunity
|
diseases resulting from the body attacking itself
Exs: lapus, rheumatoid arthritis |
|
|
Inflammation
|
the body's response characterized by damaging normal tissue when it occurse at inappropriate times or prolonged periods
|
|
|
Degeneration
|
the breaking down of tissues
|
|
|
RISK FACTORS
|
predisposing conditons which make the development of a disease more likely to occur
|
|
|
Genetic Factors

|
|
Viruses
|
-Intracellular parasites- consist of nucleic acid w/ protein coat
-Only has DNA or RNA-not both -Invades host cell and pirate orangelles and raw material -Classified by shape, nucleic acid type and method of reproduction -Not living -Multiply readily -Many diff. types |
