- engorgement of the vascular (capillary) bed
- caused by impaired venous return
- failure of forward flow (heart failure)
- dark blue or purple dicoleration of the skin and mucous membrain due to deficient oxgyen in the blood
- increase in extracellular fluid volume localized in a dependent area
- brisket (cow), lower jaw (sheep), limbs
- any fluid out of a tissiue or capillary
- b/c of inflammation
- high in protein
- will clott
- non-inflammatory accumulation of fluid in the pericardial sac
- pericardial effusion
- engorgement of the capillary bed caused by an increased arteriolar blood flow into the area/organ
- edema caused by the obstruction of the lymphatic system and an accumulation of a large amount of lymph in the affected areas
- the pathologic, physiologic, or biochemical mechanism resulting in the development of a disease or morbid process
- formation of an inappropriate clot of fibrin and/or platelets along with other blood elements on the wall of a blood or lymphatic vessel or heart
Fate of thrombi
- propagation leading to vessel obstruction
- embolization (dislodge and travel to other sites)
- dissolution (removed)
- Organization and recanalization (organization and in-growth of vessels)
- disseminated intravascular coagulation
- widespread formation of micro-vascular thrombi
- triggers fibrinolysis
- consumes the factors for both processes slowing clotting time (thrombi may have already caused extensive ischemic damage)
- consumptive coagulopathy
- usually caused by septicemia / endotoxemia, viral or immunologic injury to the endothilium
- detached intravascular solid (thrombi, tumor cells, bacteria), liquid (fat), or gaseous (air) mass that is carried by carried by the blood to a site distant form its point of origin and blocks the vessel
