Term
| In the formation of platelet plug, what is phagocytosis? |

Term
| In the formation of platelit ring, what is roling? |
|
Definition
| Neutrophils and monoctes bind to selectins (adhesion molecules) |
|
|
Term
| What is another term for adhesion molecules? |
|
Definition
|
|
Term
|
Definition
| In the formation of platelet plug, margination is more binding of adhesion molecules at damaged site causing these cells to flatten through blood vessel wall |
|
|
Term
| What is Diapedesis-transmigration? |
|
Definition
| In the formation of a blood platelet plug, this involves neutrophils and monocytes squeezing through blood vessel wall transmigration or immigration |
|
|
Term
| What are chemicals called that are released by platelets |
|
Definition
|
|
Term
| What are the stages monocytes and neutrophils go through for formation of platelet plug? |
|
Definition
Rolling, Margination, Diapedesis, Opsonization, Phagocytosis, Digestion
(rolling much dirt, oops poopy doo doo) |
|
|
Term
| What happens with intrinsic release of thromboplastin? |
|
Definition
| Large amounts of thromboplastin released tdue to collagen -platelet interaction |
|
|
Term
| What happens in extrinsic release of thromboplastin? |
|
Definition
| Small amounts of thromboplastin released by damaged tissues= NO Platelet involvement |
|
|
Term
| In Blood Clotting, what are the stages? |
|
Definition
Thromboplastin-cascade-formation of prothrombin activator. Prothrombin and prothrombinase forms Thrombin.
Thrombin and Calcium form fibrinogen and that in terms form fibrin and insoluble clot |
|
|
Term
| What is clot dissolution called? |
|
Definition
|
|
Term
| What is clot retraction called? |
|
Definition
|
|
Term
| What are the steps of clot retraction? |
|
Definition
| Plasminogen binds to endothelium. tPa released from cells with fibrin clot (controlled activation) that converts plasminogin to plasmin. Plasmin dissolves clot, cleaves fibrin, from edges of wound in clot retraction |
|
