Flashcards in VP7+8 Deck (18)
The active process of increasing the blood flow to a tissue during eg. inflammation.
A passive process due to decreased outflow from a tissue, eg. secondary to a local obstruction (something tight around a limb)
Escape of blood from vessels
Small haemorrage, 1-2mm diameter either due to a capillary rupture or clotting problem
A heamorrhar 1-3cm diameter, your regular bruise.
A heamorrhage that is covering a large area
A rupture causing a haemorrhage, eg a fracture-related haemorrhage
Increased tendency for haemorrhages after minor injuries, eg due to clotting problems.
Blood clotting, arrests bleeding from ruptured or damaged blood vessels. Either primary, secondary or tertiary.
The platelet response (turning dendritic) to exposed collagen fibers and von Willerbands factor.
Activation of the coagulation cascade by activated platelets (releasing factor 12 to activate factor 11 = thrombin).
Fibrinolysis, the breakdown of fibrin into plasmin to balance the reaction.
A formation of thrombocytes, fibrin and other blood elements in blood vessels. Will have a firm attachment to the blood vessel wall.
Coagulation of the blood as a normal post mortem change, esp found in the ventricles of the heart. Smooth surface and easily removed.
The breaking off of a tissue/aggregation that will travel in the blood stream to a distant part.
Lack of blood flow
Segmental or localised area of ischaemia (failure/reduction in blood flow).
