Document Summary
The response of an organism to ccell injury. The response to invasion of a foreign substance. Single cell organism response to injury: internalize substance/particle in a phagosome, inactive by. Complex multicellular organism: response to injury is the process of inflammation, may also include immune reactions. Purpose of inflammation: destroy, dilute, and isolate noxious agents and the consequences of cell damage, heal and reconstitute damaged tissue. Scar tissue is a always a result of inflammatory response. Inflammation does not equal infection: can have inflammation without an infectious process, inflammation is in effect a vascular response to tissue and cell injury. Multicellular organism response to injury: cell specialization, vascular system. Cell specialization: specialized functions such as. Any foreign substance that provokes the formation of an antibody. White blood cells- leukocytes: lymphocyte, monocyte, ealnophil, basophil, neutrophil. If not segmented, implies the formation of many cells in response to something. Infective dose- the number of organisms it takes to begin an infectious process.
