pathophysiology - ANSWER the study of functional/physiologic changes in the body that result from disease processes at a cellular level how is homeostasis maintained - ANSWER homeostasis is maintained by the body's blood pressure, temperature and fluid balance Carcinogenesis - ANSWER Slow process, More likely with aging Mutation,Proofreading Genetics - tumor suppressor gene ***The more times DNA is copied and a cell replicates, the greater chance an error is being made, a mistake is bei...

The principal late effects of ionizing radiation on humans include tissue damage ic effects nant disease - ANS ic effects nant disease Late or long-term effects of radiation can occur in tissues as a result of chronic exposure or tissues that have survived a previous irradiation months or years earlier. These late effects, such as carcinogenesis and genetic effects, are "all-or-nothing" effects—either the organism develops cancer or it does not. Examples of late effects of ...
