Blood Clotting

Front 1

3 main processes in Platelet Plug Formation?

Back 1

Platelet Adhesion to damaged portion of blood vessel walls

Platelet Release Response when platelets stimulate each other with newly formed extensions to release chemicals from their vesicles

Platelet Aggregation when sticky platelets adhere together forming the platelet plug

Front 2

3 mechanisms of Hemostatic Response:

Back 2

Vascular Spasm

Platelet Plug Formation

Blood Clotting

Front 3

Vascular Spasm

Back 3

damaged arteries and arterioles contract the smooth muscle in their walls to reduce blood loss

Front 4

Vascular Spasm is due to what 3 things?

Back 4

Damage of the smooth muscle in the wall of the vessel

Chemicals releaed by activated platelets

Reflexes stimulated by pain receptors

Front 5

Blood Clot

Back 5

Formed from a network of insoluble fibres called fibrin that trap formed elements

Front 6

3 main stages of Fibrin Formation:

Back 6

Production of prothrombinase;

Prothrombinase converts prothrombin (plasma protein) into thrombin (enzyme);

Thrombin converts soluble fibrinogen into insoluble fibrin, which forms the threads of the clot

Front 7

The enzyme prothrombinase can be formed in two ways:

Back 7

Intrinsic Pathway

Extrinsic Pathway
