Raised pH
A platelet is
A cell fragment from a large cell called a megakaryocyte, with potent granules for triggereing several mechanisms
A phagocyte with potent digestive enzymes
An immature inactive phagocyte
A clotting factor protein
A cell fragment from a large cell called a megakaryocyte, with potent granules for triggereing several mechanisms
Which of the following is not part of inflammation
Vascular spasm
Platelet adhesion
Extravsation after histamine release
Plasmin formation
Plasmin formation
The extrinsic clotting pathway is triggered after the release of
Tissue factor
Factor X
Platelet release of mitogens
Platelet aggregation
Tissue factor
In order for prothrombin (in the clotting cascade) to be converted to thrombin
Factor XII is required
Fibrin needs to be present
Prothrombinase (FactorXa) and calcium ions are necessary
Prothrombinase
Prothrombinase (FactorXa) and calcium ions are necessary
The final phase of the common clotting pathway involves thrombin which
Converts prothrombin to thromboplastin
Converts Fibrinogen to fibrin
Converts tissue factor to factor Xa
The final phase of the clotting cascade does not require thrombin
Converts Fibrinogen to fibrin
